Question

PLEASE ANSWER ASAP!!

1. Jake is bowling with a 8 kg bowling ball. He rolls the ball at 7 m/s, and it hits one stationary pin with a mass of 2 kg. The pin goes flying forward at 12 m/s. How fast is the bowling ball now traveling?

Answer 1

4 m/s

Step-by-step explanation:

Answer 2

We know from the principle of conservation of momentum that the momentum of the system is conserved. The total momentum of the system is 8 kg x 7 m/s = 56 kg m/s. The momentum of the pin after getting hit is 24 kg m/s. So the momentum of the bowling ball after hitting the pin is 56 kg m/s - 24 kg m/s = 32 kg m/s velocity of the ball is v = 32kg m/s / 8 kg = 4 m/s
