A1500 kg car is pushing a 4000 kg truck. the car and truck are accelerating at 2.0 m/s^2. assuming that the frictional force on the truck is negligible, what force is the truck exerting on the car?

To solve this problem we will use the Force equation according to the definition given in Newton's second law. There we have that the Force is equal to

Where,

m = mass

a = acceleration

Our values are given as

Considering that both mass are equal to one, we have that:

Therefore the truck exert a force on the car of 11kN

answer; /// the above statement is (true);

gpe = mass x gravity constant x height or… gpe = mgh

where… mass: measured in kilograms (kg)

gravity: gravity constant on earth = 10.00 m/s2

height: measured in meters (m)

gpe: measured in joules (j) or kilojoules (kj)

how do you solve gpe?

gravitational potential energy (gpe) is the energy an object has because of its position above the. ground.

gpe = mass x gravity constant x height or… gpe = mgh.
