A 1.0-kg ball with avelocity of 5m/sec hits another 1.0-kg ball that is stationary. What is the momentum of each ball before the collision?

To find the momentum of each ball before the collision, you need to know the formula for momentum and the velocity of each ball.

The formula for momentum (p) is given by:

p = m * v

Where:
p = momentum
m = mass of the object
v = velocity of the object

In this case, both balls have a mass of 1.0 kg.

The velocity of the first ball is given as 5 m/s.

So, using the formula, we can calculate the momentum of the first ball before the collision:

Momentum of the first ball (p1) = mass of the first ball (m1) * velocity of the first ball (v1)
= 1.0 kg * 5 m/s
= 5.0 kg⋅m/s

Since the second ball is stationary, its velocity is 0 m/s.

So, we can calculate the momentum of the second ball before the collision:

Momentum of the second ball (p2) = mass of the second ball (m2) * velocity of the second ball (v2)
= 1.0 kg * 0 m/s
= 0.0 kg⋅m/s

Therefore, the momentum of the first ball before the collision is 5.0 kg⋅m/s, and the momentum of the second ball before the collision is 0.0 kg⋅m/s.
