Weight = (mass) x (gravitational acceleration where the mass is)
Weight = (1360 kg) x (9.8 m/s²)
Weight = 13,328 kg-m/s²
That's 13,328 Newtons
Given:-
Mass (m) of the car = 1360 kgAcceleration due to gravity (g) = 9.8 m/s²To Find: Weight (W).
We know,
W = mg
where,
W = Weight,m = Mass &g = Acceleration due to gravity.Thus,
W = (1360 kg)(9.8 m/s²)
→ W = 13,328 N (D)

convert 288cm to Meters
Give explanation + formula
Answer:
288 cm is 2.88 meters. This is because each centimeter is 1/100th of a meter, or in other words, each meter is 100 cm. To find out cm-m, divide the amount of cm by 100 and change the unit to m.
Explanation:
formula is cm/100=m
288/100= 2.88m
an ice cube is placed in the sun later there is a puddle of water later still the.puddle is gone what kind of change has occured
Clear question is;
An ice cube is placed in the sun. Later there is a puddle of water. Later still the puddle is gone. What kind of change has occurred?
Answer:
Physical change.
Explanation:
There are two type of changes called physical change and chemical change.
In Physical changes, there is only change in the appearance of the substance and not its chemical composition. Whereas, in Chemical changes the substance changes entirely into another substance with a new chemical formula.
Now, for the ice cube, it has melted from a solid state to a liquid state. Thus, there is only a change in appearance and not its chemical composition. Thus, it's a physical change that has occurred.

What is the IMA of the following pulley system?
Answer:
5
Explanation:
An object is released from rest near a planet's surface. A graph of the acceleration as a
function of time for the object is shown for the 4s after the object is released. The
positive direction is considered to be upward. What is the displacement of the object after 2s?
Answer:
The displacement and direction of the body after 2 seconds is 10 meters downwards
Explanation:
The given information are;
From the graph, the acceleration, is seen as the horizontal line that starts from the y-coordinate, y = -5 m/s²
Therefore;
The acceleration of the body after it was released from rest = -5 m/s² with an upward direction;
Which gives, the acceleration of the body downwards = Opposite sign to the acceleration of the body upwards = 5 m/s²
The displacement, s, of the body after 2 seconds is given by the following equation of motion;
s = u·t + 1/2·a·t²
Where;
u = The initial velocity of the body = 0 m/s
t = The time duration of the displacement = 2 s
a = The acceleration of the body = 5 m/s², downwards
Therefore, by substituting the values, we have;
s = 0 × 2 + 1/2 × 5 × 2² = 10 meters
s = 10 meters
The displacement of the body after 2 seconds = 10 meters
Given that the direction of the displacement and the direction of the acceleration are the same, we have;
The displacement and direction of the body after 2 seconds = 10 meters downwards.
The displacement of the object moving downwards is 10 m.
The given parameters;
time of motion of the object, t = 2 sacceleration of the object constant = -5 m/s²The displacement of the object moving downwards (negative direction) is calculated using the second kinematic equation as shown below;
s = ut - ¹/₂at²
s = 0 - 0.5 x (-5) x (2)²
s = 10 m
Thus, the displacement of the object moving downwards is 10 m.

Which accident will be more damaging, collision between two trucks
moving with a speed 50 km/hr or collision between two cars moving with a speed of 50 km/hr? Explain.
Answer:
collision between truck
Explanation:
Answer. Collision between trucks, because more is the mass, more is the inertia and therefore more is the momentum. Mass of the trucks is more than that of cars so collision of trucks will cause more damage.

A truck covers 40.0 m in 7.10 s while uniformly slowing down to a final velocity of 2.05 m/s.
(a) Find the truck's original speed. _______ m/s
(b) Find its acceleration. __________ m/s^2
Answer:
(A) Original speed= 9.22 m/s
(B) Acceleration= -1.0099 m\s^2
Explanation:
A truck covers 40m in 7.10 secs
The truck slows down at a uniform velocity of 2.05 m/s
(A) The original speed can be calculated as follows
Vo= 2(40)/7.10 - 2.05
= 80/7.10 - 2.05
= 11.2676 - 2.05
= 9.22m/s
(B) The acceleration can be calculated as follows
a= Vf-Vo/t
= 2.05-9.22/7.10
= -7.17/7.10
= -1.0099m/s^2

An advertising balloon shaped like a giant soda can is 15 feet tall and 7 feet wide. How many cubic feet of helium will be needed to fully inflate the balloon?
Answer:
576.975 cubic feet of helium will be needed to fully inflate the balloon
Explanation:
To determine how many cubic feet of helium will be needed to fully inflate the balloon, we will determine the volume of the balloon.
From the question,
The balloon is shaped like a giant soda can.
A giant soda can is cylindrical.
Hence, we can determine the volume of the balloon shaped like a giant soda can by using the formula for finding the volume of a cylinder.
The formula for finding the volume of a cylinder is
V = πr²h
Where V is the volume of the cylinder
π is a constant (Take π = 3.14)
r is the radius of the cylinder
and h is the height of the cylinder
From the question, the balloon is 15 feet tall and 7 feet wide
Hence,
Height, h = 15 feet
Width = 7 feet
(NOTE: The width of a cylinder is the same as the diameter)
Then, diameter = 7 feet
Radius, r is given by
Radius = Diameter / 2
Then, Radius = 7 feet / 2 = 3.5 feet
∴ Radius, r = 3.5 feet
Now, for the volume of the balloon,
V = πr²h
V = 3.14 × (3.5)² × 15
V = 3.14 × 12.25 × 15
V = 576.975 cubic feet
This is the volume of the balloon.
Hence, 576.975 cubic feet of helium will be needed to fully inflate the balloon.

A competitive go-cart driver is traveling 32 m/s. He sees a caution flag go up, so he slows at a rate of -1.5 m/s^2 in 10.8 s. What is his final velocity?
Answer:
15.8 m/s
Explanation:
The following data were obtained from the question:
Initial velocity (u) = 32 m/s.
Acceleration (a) = – 1.5 m/s²
Time (t) = 10.8 s.
Final velocity (v) =?
Acceleration is simply defined as the rate of change of velocity with time. Mathematically, it is expressed as:
Acceleration (a) = [final velocity (v) – initial velocity (u)] / time (t)
a = (v – u) /t
With the above formula, we can obtain the final velocity of go-cart driver as follow:
Initial velocity (u) = 32 m/s.
Acceleration (a) = – 1.5 m/s²
Time (t) = 10.8 s.
Final velocity (v) =?
a = (v – u) /t
– 1.5 = (v – 32) / 10.8
Cross multiply
(v – 32) = –1.5 × 10.8
v – 32 = – 16.2
Collect like terms
v = – 16.2 + 32
v = 15.8 m/s
Therefore, the final velocity of go-cart driver is 15.8 m/s.
