Car is accelerating with acceleration = 20 m/s2. A box of mass m = 10 kg that is placed inside the car it is put in contact with the vertical wall of car as shown. The friction coefficient between the box and the wall is \[\mu =0.6\].

The contact force between the vertical wall and the box will be 100 N

The acceleration of the box will be \[10\,m/{{\sec }^{2}}\]

The friction force acting on the box will be 100 N
