Question

On roller blades you horizontally toss a ball away from you. The mass of the ball is one tenth of your mass. Compared with the velocity you give to the ball, your recoil velocity will ideally be_______.

Answer 1

one tenth of the velocity of the ball.

Step-by-step explanation:

Recoil velocity is the velocity at which a person's body moves when he fires a bullet or an object with a particular mass and speed. The following formular is used to calculate recoil velocity.

mv = MV.....................equation 1

where:

• m is mass of object shot or tossed
• v is the velocity of object fired or tossed
• M is mass of person firing the object
• V is the recoil velocity of the person firing the object

From the question we know that
`m= 1/10M` . so we substitute this into equation 1. we get;

`1/10M*v =MV`

`1/10v=V`

therefore your recoil velocity will be one tenth the velocity of the ball
