A 2kg block sits on on a cart of mass 8kg. The coefficient of static friction between the block and cart is fs = 0.3. (Suppose the cart rolls on the floor with little friction.) 2 kg 8 kg 2. (a) If you exert a force of 20 Newtons on the cart push it with your hand what is its acceleration? (b) In that same situation, what is the size and direction of the friction force by the cart on the block? (c) Now suppose you push the cart with a force of 40 Newtons. What can you say now, about the acceleration of the cart and the force on the block? A 2kg block sits on on a cart of mass 8kg.
