A force of 80 Newtons, East and 20 Newtons, North acts on a 25 kg package which is initially at rest. A bare hand stops the baseball in 0.05 seconds. Show mathematically why catchers wear mitts.
Catchers wear mitts to help increase the stopping time and decrease the force on their hands.
Had the time above been 0.50 seconds, the force would only be -24 N. 3. A 60 kg rock climber slips and falls a distance of 3.0 meters before the safety rope begins to stop him. The rope stretches as it stops him. It takes 0.75 seconds to stop him. It collides, and attaches to a stationary train of 4 cars, each with the same mass of 2 tons.
