A block of mass 10 kg is attached to the end of a horizontal spring with spring constant k = 1200 Nm-1. The block is assumed to be sitting on a frictionless horizontal surface.
a) Illustrate a sketch of the system.
b) What force must be applied to the block to compress the spring a distance of 35 mm?
c) What energy is needed to compress the spring by 35 mm?
d) If the spring is compressed from its zero position to 70 mm in a period of 2 s what is the Power needed to do this?
e) If the spring is compressed to 70 mm and then suddenly let go what will the start acceleration of the block be?
