Question

A truck of mass 5000 kg rolls down from a hill it covers 200m in 10s then the force acting is what

Answer 1

Answer:

Explanation:

In this scenario, the truck rolls down the hill because it is at a higher potential and the slope allows a component of gravitational force to act on the car.

Parallelly, the car experiences a frictional force in the opposite direction of motion of the car.

And of course, the truck has its own weight (which is a force that acts downwards) and a Normal force acting perpendicular to the surface of the hill.

Answer 2

Answer:The force exerted by the truck is 100000 N

Explanation:

Here, The force is momentum ,

as momentum is the product of mass and its velocity m × v

velocity of the truck is $200/10$$ms^{-1}$=20$ms^{-1}$

momentum = m×v

therefore 5000 ×20 N$Kgms^{-1}$ = 100000N
