Question

What is the momentum of a 50-kilogram ice skater gliding across the ice at a speed of 5 m/s?

Answer 1

momentum (kg m/s) = mass (kg) x velocity (m/s).

momentum is a vector quantity but as you are given the speed in this question then you can only find the magnitude of the momentum.

Answer 2

\[p=mv\]
where p is momentum, m is mass, and v is velocity. In this problem only a speed is given not a velocity so plug in the speed of 5 m/s into v in the equation.

Answer 3

ie.\[p=(5 m/s)(50 kg)\]

Answer 4

\[=250 kg*m/s\]

Answer 5

thats the momentum
