Question

A teacher pushes a cart, while a student pushes a second, heavier cart

with the same amount of force. If the student's cart has three times the
mass as the teacher's, which of the following is true? *

Answer 1

frictional force acting on the cart 450 N.

Given:

mass of cart = 50 kg

acceleration = 3

To find:

Frictional force = ?

Formula used:

F - = 600 N

F = ma

= frictional force

Solution:

Force on the block is given by,

F - = 600 N

F = ma

= frictional force

= 600 - m a

= 600 - (50 × 3)

= 600- 150

= 450 N

According to the given data the frictional force acting on the cart 450 N.
