A 10.67 kg bowling ball has speed 4.35 m/s before hitting the floor. A(n) 66.5 g golf ball flies at much higher speed, so the two balls have exactly same kinetic energy. What is the speed of the golf ball?
Note: neglect rotation of either ball. Answer in units of m/s.

  • physics -

    0.5m1*V1^2 = 0.5m2*V2^2.
    5.335*(4.35)^2 = 0.03325*V2^2
    0.03325V2^2 = 100.95
    V2^2 = 100.95 / 0.03325 = 3036
    V2 = 55.1 m/s.
