Answer:
For example, when a car travels at a constant speed, the driving force from the engine is balanced by resistive forces such as air resistance and friction in the car's moving parts. The resultant force on the car is zero.

H = 109.2 TJ.
Explanation:
Please see the attachment below.
Answer:
The force of the impact would be smaller
Explanation: Examples:
If the force is big then the time would be small (2500N of Force = 10 seconds)
If the force is small then the time would be big (250N of Force = 50 seconds)
Impulse/Collision -> [Ft] = [M (vf-vo)] <- Change in momentum
Answer:
0.44807175m
Explanation:
k = Spring constant =
(Assumed, as it is not given)
g = Acceleration due to gravity = 9.81 m/s²
Total mass is

The total weight will balance the spring force

The springs are compressed by 0.44807175m
