QUESTION:

During a circus act, an elderly performer thrills the crowd by catching a cannon ball shot at him. The cannonball has a mass of 10.0 kg and the horizontal component of its velocity is 8.00 m/s when the 65.0-kg performer catches it. If the performer is on nearly frictionless roller skates, what is his recoil velocity?

QUESTION:

During a circus act, an elderly performer thrills the crowd by catching a cannon ball shot at him. The cannonball has a mass of 10.0 kg and the horizontal component of its velocity is 8.00 m/s when the 65.0-kg performer catches it. If the performer is on nearly frictionless roller skates, what is his recoil velocity?

ANSWER:

Step-by-step solution In the given problem a circus act is performed of catching a cannon ball. Now as per the given data find the recoil velocity of the performer if the performer is on nearly frictionless roller skates. Step 1 of 2 For a collision, the momentum will be conserved. So, …… (1) Here is the mass of ball, is the mass of performer, is the velocity of ball, is the velocity of performer and is the velocity after collision.
