An intern pushes a 97 kg computer cart down the hall. the cart starts from rest and travels 27.634 m in 12.33 s. what force does he apply to the cart?

Explanation:

       A 97 kg cart is pushed down the hall. The cart starts from rest. The cart travels 27.634 m in 12.33 sec. Since not much is mentioned about the pushing force, it is assumed constant.

       So, the cart is under a uniformly accelerated linear motion.

       Also, since nothing is mentioned about friction, it is assumed that the surface is smooth.

       Consider the equation of motion,

Here is the distance covered, is the initial velocity, is the acceleration, is the time.

       On substituting the values,

So, force applied =

∴ Force applied on the cart = 35.26 N
