if a 50.0-kg mass weighs 554 n on the planet saturn, calculate saturn’s radius
Answer:
17.35 × 10^(-6) m
Explanation:
Mass; m = 50 kg
Weight; W = 554 N
Now, we know that;
W = mg
Thus; 554 = 50g
g = 554/50
g = 11.08 m/s²
Also, we know that;
mg = GMm/r²
g = GM/r²
Making t the subject gives;
r = √(GM/g)
G has a constant value of 6.67 × 10^(-11) Nm²/kg²
r = √(6.67 × 10^(-11) × 50/11.08)
r = 17.35 × 10^(-6) m
The radius of the saturn is [tex]\bold {17.35 x 10^{-6 }m}[/tex] if a 50.0-kg mass weighs 554 N.
From Newton's second law,
W = mg
554 = 50 x g
g = 554/50
g = 11.08 m/s²
Now, Newton's law of gravitation
[tex]\bold {F=G{\dfrac{m_1m_2}{r^2}}}[/tex]
Where,
F = force
G = gravitational constant = 6.67 x 10^-11 N.m²/kg²
m1 & m2= mass = M = 50 kg
r = distance between centers of the masses
Put the values and solve it for r,
[tex]\bold {r = \sqrt {(6.67 x10^{-11} \times \dfrac {50}{11.08}}}\\\\\bold {r = 17.35 x 10^{-6 }m}[/tex]
Therefore, the radius of the saturn is [tex]\bold {17.35 x 10^{-6 }m}[/tex] if a 50.0-kg mass weighs 554 N.

A 1600 kg car with the brakes applied comes to a stop in 4.20 seconds. During these 4.20 seconds the force of friction slowing down the car is 3900 N. What is the change in momentum of the car?
Answer:
The change in momentum of the car is 16380.8 kg.m/s
Explanation:
Given;
mass of the car, m = 1600 kg
time of motion, t = 4.20s
force of friction on the car, F = 3900 N
final velocity of the car after the brakes were applied, v = 0
The initial velocity of the car during the motion is calculated as;
[tex]F = ma = \frac{mu}{t} \\\\mu = Ft\\\\u = \frac{Ft}{m} \\\\u = \frac{3900\times 4.2}{1600} \\\\u = 10.238 \ m/s[/tex]
The change in momentum of the car is calculated as;
ΔP = mu
ΔP = 1600 x 10.238
ΔP = 16380.8 kg.m/s

When a 5 kg rock is dropped from a height of 6 m on Planet X, it loses 24 J of GPE. What is the acceleration due to gravity on Planet X?
Answer:
g = 1.25m/s²
Explanation:
Given the following data;
Mass = 5kg
Height = 6m
Gravitational potential energy = 24J
To find the acceleration due to gravity;
Potential energy can be defined as an energy possessed by an object or body due to its position.
Mathematically, potential energy is given by the formula;
[tex] P.E = mgh[/tex]
Where,
P.E represents potential energy measured in Joules.
m represents the mass of an object.
g represents acceleration due to gravity measured in meters per seconds square.
h represents the height measured in meters.
GPE = mgh
Substituting into the equation, we have;
24 = 5*6*g
24 = 30g
g = 30/24
g = 1.25m/s²
Therefore, the acceleration due to gravity on Planet X is 1.25m/s².
Answer:
g=0.8m/s^2
Explanation:
M=5kg
h=6m
GPE=24J
GPE=Mgh
g=GPE/Mh
g=24J/(5kg)(6m)=0.8
g=0.8m/s^2

Consider a 2,000 kg car traveling 10 m/s toward another car.After the two cars collide, they couple together and move along at 6 m/s. What is the mass of the second car?
Can someone please solve and explain,I don’t understand:/
Answer:
I haven't learnt physics at all yet but I'll try.
After the two cars collide, they move at 6 m/s.
This tells us that the 2nd car which collided with the first car which is 2000 kg is much heavier than the 1st one, if the second one was lighter, the two cars coupled together speed would be much more than just 6 m/s.
Refer to explanation for working.
Explanation:
Now find out how much g or kg is the 2nd car more than the 1st.
2000 ÷ 10 = 200 (I don't really know how to explain this part)
10 - 6 = 4 (Difference for 1st car average speed per second and the coupled cars average speed per second)
200 x 4 = 800
2000 + 800 = 2800 kg

If you use the same force to push a motorcycle as you would push a bike which one would have more acceleration and why explain using Newton's second law
Answer:
The bike would have more acceleration
Explanation:
Accourding to newtons first law a force is equal to its mass multiplied by its acceleration (f=ma) therefore an object with a higher mass compared to an object with a lower mass would experience less acceleration.
Eg.
F=50N
Motorbike M=200kg
F=ma
50=200 x a
50/200=a
0.25m/s/s =a
Bike M=35kg
F=ma
50=35 x a
50/35= a
1.43m/s/s=a
Answer:
the bike
Explanation:
it has less mass than the motorcycle so so it would have more acceleration

Earth.
The speed of light is 2.99792 x 108 m/s.
How long does it take for its light to reach
us?
Answer in units of min.
Answer:
It takes the Sun's light 7.17 minutes to reach us.
Explanation:
We can calculate the time that takes the light to reach us by using the following equation:
[tex] t = \frac{d}{c} [/tex]
Where:
d: is the distance = 1.29025x10⁸ km = 1.29025x10¹¹ m
c: si the speed of light = 2.99792x10⁸ m/s
Hence, the time is:
[tex] t = \frac{d}{c} = \frac{1.29025 \cdot 10^{11} m}{2.99792 \cdot 10^{8} m/s} = 430.38 s = 7.17 min [/tex]
Therefore, it takes the Sun's light 7.17 minutes to reach us.

Julieta kicks a 0.2 kg soccer ball already rolling in the same direction at 2.5 m/s. The ball leaves her foot at a speed of 20 m/s after the kick
Answer:
3.5kgm/s
Explanation:
We can calculate the momentum of Julieta
momentum = m(v-u)
Momentum = 0.2(20-2.5)
Momentum = 0.2(17.5)
Momentum = 3.5
Hence the momentum of Julieta is 3.5kgm/s
The first charge is pulling on the second. Is the second pulling on the first? Explain your reasoning
Answer:
law of action and reaction.
Explanation:
In Newton's three laws it is established that forces act in pairs, if one body interacts with another the second interacts with the first, this is the so-called law of action and reaction.
In this case, when the first load pulls on the second, the second pulls on the first, the two forces are not canceled because each one is applied to a different body.
Therefore the magnitude of the forces is the same, but the direction is opposite and each one is applied in a body
An electric force is an attractive or repulsive interaction. Newton's laws of motion define how it affects things, just like any other force. Yes, the second pulling on the first.
How does Newton's third law explain in terms of electricity?An electric force is an attractive or repulsive interaction between any two charged things. Newton's laws of motion define how it affects things, just like any other force.
The motion of objects under the influence of such a force or combination of forces is studied using Newton's laws.
The analysis generally starts with the creation of a free-body diagram in which the kind and direction of the various forces are represented by vector arrows.
Newton's laws of motion define how it affects things, just like any other force. Hence Yes, the second pulling on the first.

A 10 kg bowling ball would require what force to accelerate down an alley at a rate of 3 m/s2? what is the net force?
Answer:
a. Force = 30N
b. Fnet = 128N
Explanation:
Given the following data;
Mass = 10 kg
Acceleration = 3m/s²
a. To find the force;
Force = mass * acceleration
Substituting into the equation, we have
Force = 10 * 3
Force = 30N
b. To find the net force;
Mathematically, net force is given by the formula;
Fnet = Fapp + Fg
Where;
Fnet is the net force. Fapp is the applied force. Fg is the force due to gravitation.We know that acceleration due to gravity is equal to 9.8m/s²
To find the gravitational force;
We know that acceleration due to gravity, g = 9.8m/s²
Fg = mg = 10*9.8 = 98N
Substituting into the equation, we have;
Fnet = 30 + 98
Fnet = 128N
