Answer:
Distance = 7 meters.
Explanation:
Given the following data;
Force = 50N
Kinetic energy = 350J
To find the distance;
We know that energy possessed by an object over a distance represents the work done by the object.
Mathematically, work done is given by the formula;
Workdone = force * distance
Substituting into the formula, we have;
350 = 50 * distance
Distance = 350/50
Distance = 7 meters.

What is the vertical motion of an object?
Answer:
Vertical motion is the movement of an object in a straight line.
When an object is thrown up, it always comes down, as it is affected by the acceleration due to gravity. This is called as vertical velocity.

Explanation:
When a 4-kg ball is thrown upwards at 40 m/s, at what
height is the potential energy equal to the kinetic
energy
Answer:
the height of the potential energy is 3,200 J
Explanation:
The computation of the kinetic energy is shown below:
Kinetic energy = 1 ÷ 2 × mass × velocity^2
= 1 ÷ 2 × 4 kg × 40 m/s^2
= 3,200 J
Hence the height of the potential energy is 3,200 J

If 2.2 lbs = 1.0 kg, and Megan Progress weighs 130 lbs, what is her weight in newtons?
(F= ma). where acceleration due to gravity is 9.8 m/s2
Answer:
Force = 2802.8 Newton
Explanation:
Given the following data;
Mass = 130 lbs
But, 2.2 lbs = 1.0 kg
130 lbs to kg = 130 * 2.2 = 286 kg
Acceleration due to gravity = 9.8m/s²
To find the force in Newton;
Force = mass * acceleration due to gravity
Force = 286 * 9.8
Force = 2802.8 Newton

3) A 6.1 kg bowling bowl and a 7.2 kg bowling ball rest on a rack. If the force of gravity pulling each
bowling ball toward the other is 3.1 X 10° N, what is the separation between the balls?
The distance of separation of the balls is 3.07×10⁻⁵ m.
To Solve the question, we use the formula below.
Formula:
F = GMm/r²...................... Equation 1Where:
F = Force of gravityG = Universal constantM = mass of the bigger bowling ballm = mass of the smaller bowling ballr = Distance of separation between the balls.
Make r the subject of the equation,
r = √(GMm/F)................. Equation 2From the question,
Given:
F = 3.1 NM = 7.2 kgm = 6.1 kgG = Constant = 6.67×10⁻¹¹ Nm²/kg².Substitute these values into equation 2
r = √(7.2×6.1×6.67×10⁻¹¹/3.1)r = √(9.45×10⁻¹⁰)r = 3.07×10⁻⁵ mHence, the distance of separation of the balls is 3.07×10⁻⁵ m.

A car and driver weighing 6900 N passes a sign stating “Bridge Out 26.6 m Ahead.” She slams on the brakes, and the car decelerates at a constant rate of 10 m/s2 .
The acceleration of gravity is 9.8 m/s2 .
What is the magnitude of the work done stopping the car if the car just stops in time to avoid diving into the water?
Answer in units of J.
Answer:
187286 J
Explanation:
Lets work backwards. We are trying to find work, and are given kinematic variables. We know that the W = Fd, and since we already have d, all we need to find is F.
Using F = ma:
We know [tex]mg = W = 6900[/tex], and so solving for m, we get 704.082kg.
Now we can plug in the decelleration of the car with the mass in order to find the force against the car(by the brake).
[tex]F = 704.082*(-10) = -7040.82[/tex]
Now plugging this into W = Fd, we get:
[tex]W = (7040.82)*26.6 = 187286J[/tex]
This is just the magnitude, but if you wanted to find the sign of W, you would use the fact that the force is going in the opposite direction of the car, so work would be negative. However, this question asks only for the magnitude, so we ignore the final sign.

Two charged balls are 10 cm apart. One is positively charged, and the other is negatively charged.
Explain how the electric field and/or force would change if both balls had positive charge.
Answer:Explanation: The field lines of the electric charges extend from the positive to negative side charge. ... The force between the two charged balls is attractive. It is directly proportional to the product of their charges and inversely proportional to the magnitude of the distance between them.

A cuboid made of spruce wood has the edge lengths a = 20 cm, b = 25 cm and c = 30 cm. It is to be pressed completely under the water surface and then held in the water.
a) Calculate the volume V of the cuboid!
b) With what force F must the cuboid be held in the water? (Density of spruce wood: p F = 500 kg/m³: Density of water: p w = 1000 kg/m³: g=9.81 N/ kg.)
Answer:
a) The volume of the cuboid is 0.015 m³
b) The force that must be applied for the cuboid to be held in the water is 141.15 N
Explanation:
The given parameters of the cuboid made of spruce wood are;
The edge lengths dimensions of the cuboid are, a = 20 cm, b = 25 cm, c = 30 cm
The location of the cuboid = Pressed completely under water;
The density of spruce wood, ρF = 500 kg/m³
The density of water, ρw = 1,000 kg/m³
The acceleration due to gravity, g ≈ 9.81 N/kg
a) The volume of a cuboid = Length × Breadth × Height
Taking , a = The length of the cuboid, b = The breadth of the cuboid, and c = The height of the cuboid, we have;
The volume of the cuboid, V = a × b × c = 20 cm × 25 cm × 30 cm = 15,000 cm³
The volume of the cuboid, V = 15,000 cm³ = 0.015 m³
b) The force 'F' that must be applied for the cuboid to be held in the water is given by the up thrust on the cuboid by the water
∴ F = The up thrust on the cuboid by the water = The weight of the water displaced
The weight of the water displaced, Ww = mw × g = ρw × Vwater × g
Where;
mw = The mass of the water = ρw × Vwater
Vwater = The volume of the water displaced = The volume of the cuboid = V
∴ Vwater = V = 0.015 m³
∴ Ww = 1,000 kg/m³ × 0.015 m³ × 9.81 N/kg = 147.15 N
The force that must be applied, F = Ww = 147.15 N
The force that must be applied for the cuboid to be held in the water = 141.15 N.

The same strength force was exerted in the same direction on both Object A and Object B. Why did Object A go faster than Object B?
Answer:
[tex]m_B > m_A[/tex]
the mass of body B must be greater than the mass of body A
Explanation:
Newton's second law establishes a linear relationship between the force, the mass of the body and its acceleration
F = m a
a = F / m
Let's analyze this expression tells us that the force is of equal magnitude for the two bodies, but body A goes faster than body B, this implies that it has more relationships
a_A > a_B
[tex]\frac{F}{m_A} > \frac{F}{m_B}[/tex]
[tex]m_B > m_A[/tex]
Therefore, for this to happen, the mass of body B must be greater than the mass of body A
