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

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

as a general rule, scissors have blades less than 6 in (15 cm) long and usually have handles with finger holes of the same size. shears have blades scissors used to cut hair or fabric must be much sharper
