Question

How much impulse would be required to insrease the velocity of a 20 kg object moving with 21. initial velocity 20 m/s to a final velocity of 50 m/s? Which has greater momentum, an S kg bowling ball moving at a speed of 2 m's, or a ping pong ball moving at a speed of 200 m/s? 22. n 8 kg bowling ball, moving with velocity 2 m's to the right, collides with a 20 g golf ball moving to the left at 2 m/s. Calculate the total momentum of the system after the collision Sko 24. In Problem #23, calculate the total kinetic energy of the system before the collision. In Problem #23, calculate the final velocity of the golf ball after the collision, assuming that th final velocity of the bowling ball is 1.98 m/s and the collision is elastic 25.

Explanation / Answer

(21). impulse = m (Vf - Vi) = 20*(50-20) kg*m/s = 600 kg*m/s

The value of impulse is 600 kg*m/s
