Q. A large wheel is coupled to a wheel with half the diameter. How does the rotational speed of the smaller wheel compare with that of larger wheel? How do the tangential speeds at the rims compare (assuming the belt doesn't slip)?

Q. A 2.5 kg block is placed on a vertical spring (K=5.00x10^3-N/m) and pushed downward compressing the spring an additional 10 cm. As the block is free, it leaves the spring and continues to travel upward. What height above the point of release will block reach if the air resistance is negligible?
