A spring is placed horizontally on a frictionless table. The spring constant of the spring is 50 N/m, and it is
compressed 0.1 m by a 2 kg block.
a. How much energy is stored in the spring?
b. When the spring expands back to its resting position, it pushes the block away. What is the kinetic
energy of the block as a result of this force?
c. What is the velocity of the block as it is pushed away by the spring?

Arunner is training for an upcoming marathon by running around a 100-m-diameter circular track at constant speed. let a coordinate system have its origin at the center of the circle with the x-axis pointing east and the y-axis north. the runner starts at (x, y) = (50 m, 0 m) and runs 2.5 times around the track in a clockwise direction.
