What is the magnitude of the momentum of the 0.057-kg tennis ball when it travels at a speed of 29 m/s? Earth is the frame of reference.

To calculate the magnitude of momentum, we need to use the formula:

Momentum (p) = mass (m) × velocity (v)

In this case, the mass of the tennis ball (m) is given as 0.057 kg, and the velocity (v) is given as 29 m/s.

So, we can substitute these values into the formula:

p = 0.057 kg × 29 m/s

Now, let's calculate the value:

p = 1.653 kg·m/s

Therefore, the magnitude of the momentum of the tennis ball is 1.653 kg·m/s.

momentum = m v = .057 * 29

the units are kg·m/s
