Question

The linear momentum of a ball of mass 5 gram is 0.5km/s. Find the velocity

Answer 1

Answer:

10 m/s

Explanation:

Momentum = mv

=> v = momentum /mass

=> v = 0.5/0.05

=> v = 10

Answer 2

Answer:

100 m/s

Explanation:

Given :

• Mass of the ball = m = 0.005 kg

• Linear momentum of the ball = p = 0.5 kg m/s

To find :

• Velocity of the ball

Linear Momentum = Mass×velocity

0.5 kg m/s = 0.005×v

v = 0.5/0.005

v = 100 m/s

The velocity of the ball in m/s is equal to 100 m/s

Formula :

• P=m×v

• P=momentum

• M=mass

• V=velocity
