a small 0.14kg animal sits on a 0.55kg cart at rest on a frictionless surface. the cart is attached to a spring which it also attached to a wall. the animal suddenly jumps off the cart horizonally with a velocity of 2.5 m/s, causing the cart to being to move. the spring constant is 3.2 N/m. A) find the magnitude of velocity of the cart after the animal jumps off. B) find the magnitude if maximum compression of the spring after the cart starts to move. C) find the period if the vibrational movement of the cart. D) find the magnitude of maximum acceleration of the cart and the state where it occurs.
