Question

A car is accelerating with acceleration = 20 m/s2

. A box of mass 10 kg is placed inside the car

is in contact with the vertical wall as shown. The friction coefficient between the box and the

wall is m = 0.6 and take g = 10 m/s2

.

20m/s2

µ =0.6

(A) The acceleration of the box will be 20 m/s2

(B) The friction force acting on the box will be 100 N

(C) The contact force between the vertical wall and the box will be 100Ö5 N

(D) The net contact force between the vertical wall and the box is only of electromagnetic in

nature​
