a) A 1.34 kg mass is sliding across a frictionless surface. It then encounters a happy little spring, as shown in the figure. By how much will the mass compress the spring? (The mass is moving at 2.1 meters per second, and the spring constant is equal 50 N/m) happy spring 0. 343 b) How long will it take to compress all the way after the box collides with it?
