A 70kg person running at an initial speed of 4m/s jumps onto a120kg cart initially at rest. The person slides on the cart's topsurface and finally comes to rest relative to the cart. Thecoefficient of kinetic friction between the person and the cart is0.400. Friction between the cart and ground can be ignored.
(a) Determine the displacement of the person relative to theground while he is sliding on the cart.
(b) Determine the displacement of the cart relative to theground while the person is sliding.
