How fast would a 4.5 kg rock be traveling if it's momentum was 6.7 kg*m/s?

The momentum is defined as:


p=mv

where m is the mass and v is the velocity of the object.

Plugging the values given and solving for v we have:


\begin{gathered} 6.7=4.5v \\ v=(6.7)/(4.5) \\ v=1.49 \end{gathered}

Therefore the rock was moving at 1.49 m/s (rounded to two decimals)
