Q1. A 310 kg weather rocket is loaded with 100 kg of fuel and fired straight up. It accelerates upward at 28.0 m/s2 for 32.0 s, and then runs out of fuel. Overlook any air resistance effects.

Q2. A man is riding on a flatcar travelling at a constant speed of 9.10 {rm{ m/s}}. He wishes to throw a ball through a stationary hoop 4.90 {rm m} above the height of his hands in such a manner that the ball will move horizontally as it passes through hoop. He throws the ball with a speed of 10.8 {rm{ m/s}} respecting himself.
