During a circus act, an elderly performer thrills the crowd by catching a cannon ball shot at him. The cannon ball has a mass of 72.0 kg and its horizontal component of velocity is 6.50 m/s just before the 65.0 kg performer catches it. If the performer is initially motionless on nearly frictionless roller skates, what is his speed immediately after catching the cannon ball

3.416 m/s

Explanation:

Given that:

mass of cannonball = 72.0 kg

mass of performer = 65.0 kg

The horizontal component of the ball initially = 6.50 m/s

the final velocity of the combined system v = ????

By applying the linear momentum of conservation:

v = 3.416 m/s

speed

ratio of distance traveled to time interval

net force

vector sum of forces on object

object

source of diverging light rays either luminous or illuminated
