When spiking a volleyball, a player changes the velocity of the ball from 4.2m/s to -24m/s along a certain direction. If the imp
dedylja [7]

Answer:

The mass of the volleyball is 0.32 kg.

Explanation:

Given that,

Initial speed of the ball, u = 4.2 m/s

Final speed of the ball, v = -24 m/s

The impulse delivered to the ball by the player is -9.3 kg-m/s.

To find,

Mass of the volleyball.

Solution,

The change in momentum of the volleyball is equal to the impulse delivered to the ball. It is given by :

J=m(v-u)

m=\dfrac{J}{(v-u)}

m=\dfrac{-9.3\ kg-m/s}{(-24-4.2)\ m/s}

m = 0.32 kg

So, the mass of the volleyball is 0.32 kg.
