Question

A 34.75 kg boulder is rolling down a hill. If, at one moment, the boulder has a momentum of 239.5 kg ⋅ m/s, what is its velocity at that time?

Answer 1

Answer:

Velocity = 6.89 m/s

Explanation:

The equation for momentum: $Momentum=(Mass)(Velocity)$

Substitute the given information into the equation and solve for velocity.

$239.5=34.75(Velocity)\\\frac{239.5}{34.75}=\frac{34.75(Velocity)}{34.75\\}\\6.89=Velocity$
