Two Physics Questions: + additional points

1. A 65-kg male ice skater is facing a 45-kg female ice skater. They are at rest on the ice. They push off each other and move in opposite directions. The female skater moves backwards with a speed of 3 m/s. Determine the post-impulse speed of the male skater.2. A 50-gram tennis ball is loaded into a 2-kg homemade cannon. The cannon is at rest when it is ignited. Immediately after the impulse of the explosion, a photogate timer measures the cannon to recoil backwards a distance of 6 cm in 0.02 seconds. Determine the post-explosion speed of the cannon and of the tennis ball (watch your units!)Post-explosion speed of the cannon: Post-explosion speed of the tennis ball:
