A 7.0 kg bowling ball traveling at 2.0 m/s collides with a stationary 0.5 kg beach ball in
an elastic collision. The bowling ball leaves the collision with a velocity of 1.5 m/s
traveling in the same direction as the beach ball.
Calculate the speed of the beach ball.
A 1.0 m/s
B 2.0 m/s
C 3.5 m/s
D 7.0 m/s
Question
Answer:
D 7.0 m/s
Explanation:
MU+mu=MV+mv
7×2+0.5×0 =7×1.5+0.5×v
14+0=10.5+0.5v
14-10.5= 0.5v
3.5=0.5v
0.5v0.5 =3.5/0.5
v= 7m/s
Answer:
70
