A rocket of total mass 3180 kg is traveling in outer space with a velocity of 115 m/s toward the Sun. It wishes to alter its course by 31.0°, and can do this by firing its rockets briefly in a direction perpendicular to its original motion. If the rocket gases are expelled at a speed of 1770 m/s, how much mass must be expelled? kg A 0.145 kg baseball pitched at 36.0 m/s is hit on a horizontal line drive straight back toward the pitcher at 52.0 m/s. If the contact time between bat and ball is 1.00 10-3 s, calculate the average force between the ball and bat during contact. N
