Question

A motor can of mass 60 kg in 15 second . Find the acceleration and the force exerted on it .​

Answer 1

Explanation:

See the maximum static friction that can act on the body is Umg = 0.5×60×9.8=294N

now since the force is just above 300 N, the body will translate and the type of friction now will be kinetic instead of static.

Hence the net acceleration is

294−0.4×60×9.8/60=0.98m/s
