A 3.00-kg box is sliding along a frictionless horizontal surface with a speed of 1.8 m/s when it encounters a spring. (a) Determine the force constant of the spring, if the box compresses the spring 5.20 cm before coming to rest. N/m (b) Determine the initial speed the box would need in order to compress the spring by 1.60 cm.
