Question

A 70 kg ice skater skates to the right on an ice rink. If they have a momentum of 400kg*m/s, what is the skater's velocity?

Answer 1

The momentum (p) of an object is defined as the product of its mass (m) and its velocity (v):

p = m * v

Rearranging this equation, we can solve for the velocity:

v = p / m

Plugging in the given values, we get:

v = 400 kg*m/s / 70 kg

v = 5.71 m/s

Therefore, the skater's velocity is 5.71 meters per second to the right.
