A 1.40 kg block slides with a speed of 0.950 m/s on a frictionless horizontal surface until it encounters a spring with a force constant of 734N/m. The block comes to rest after compressing the spring 4.15 cm. Find the spring potential energy, U, the kinetic energy, K and the total mechanical energy of the system, E, for compressions of (a) 0cm (b) 1.00 cm (c) 2.00 cm (d) 3.00 cm (e) 4.00 cm
