In the first question, we have two blocks placed in contact on a smooth horizontal surface with two forces applied on either side. Find the internal contact force a body acts on the other.

In the second question, we have a truck delivers constant power and experiences constant frictional force. It accelerates non-linearly and we are to find the maximum velocity achieved.

In the third question, we have three crates stacked above one another in a lift that is accelerating upwards. Find the internal normal contact force a body acts on the other.
