The strain energy of a catapult extended by 1metre is 20J. When x=1m, A 1kg block is catapulted a distance of 2.5metres from the point of release along a horizontal floor.
a. What is the magnitude of the force of friction between the block and the floor?
b. What is the maximum kintetic energy of the block?
