A ball moving at a velocity of 10 meters/second has a momentum of 8.0 kilogram meters/second. What is its mass?

m * v = 8.0

m * 10 = 8.0

m = 0.8 kg (about a pound)

To find the mass of the ball, you can use the formula:

Momentum = mass × velocity

Given that the momentum is 8.0 kg·m/s and the velocity is 10 m/s, you can rearrange the formula to solve for mass:

mass = momentum / velocity

Substituting the given values into the equation:

mass = 8.0 kg·m/s / 10 m/s

mass = 0.8 kg

Therefore, the mass of the ball is 0.8 kilograms.

To find the mass of the ball, we can use the formula for momentum:

Momentum = mass × velocity

Given that the momentum is 8.0 kilogram meters/second and the velocity is 10 meters/second, we can rearrange the formula to solve for mass:

mass = momentum / velocity

mass = 8.0 kilogram meters/second / 10 meters/second

mass = 0.8 kilograms

Therefore, the mass of the ball is 0.8 kilograms.
