A lab cart is moving on a straight horizontal frictionless track. The above graph of velocity versus time for the cart is given above. During some intervals a force is applied to the cart. Assume the cart has a mass of 0.5 kg. Rank the magnitude of the applied force for each of the following intervals.

two blocks a and b are in contact on a horizontal frictionless surface

Ques:

Two blocks (A and B) are in contact on a horizontal frictionless surface. A 40N constant horizontal force is applied to A. The mass of A is 5.0kg and the mass of B is 20kg. What is the magnitude of the force of A and B?
