While at a baseball game, you catch a foul ball with your bare hand. Less damage to your hand occurs if you begin your catch with your hand extended towards the incoming ball; this is so there will be space to gradually pull your hand and the ball backward. Using the ideas of impulse, force, time and momentum, explain why this is so. *

Awater balloon launcher uses an elastic band with a spring constant of 115 n/m to use thee launcher you stretch thee band back with a balloon n it the water balloons have a mass of 1.3 kg a) if you stretch the band by 0.8 m, what elastic force will the band exert? b) with the band stretched 0.8 m, how much elastic potential energy is stored in the spring? c) if you release the band, it pushes forward. what is the kinetic energy of the balloon when it reaches the natural length of the band? d) what is the speed of the balloon when it reaches the natural length of the band?
