Question

Help please!

A mother pulls horizontally along the handle of a baby cart of 10.0 kg mass with a force of 60 N. The frictional force between the wheels and the ground is 25 N.


Determine the normal force (also known as the support force).

Answer 1

Ok, so I'll assume that g=10.

In order to find the normal force all you need is the Weight since we know we are moving ok a horizontal surface.

weight = m*g = 10*10 = 100N

N-W=0

N=W

N=100N

Hope I helped :)
