## Physics for Scientists and Engineers: A Strategic Approach with Modern Physics (3rd Edition)

In general, the momentum is $p = mv$. We can equate the momentum of the bicycle and the momentum of the car to find the required speed $v$ of the bicycle. $p_{cyclist} = p_{car}$ $(100~kg)~v = (1500~kg)(5.0~m/s)$ $v = \frac{(1500~kg)(5.0~m/s)}{100~kg}$ $v = 75~m/s$ The bicycle and the car have the same momentum when the bicycle is moving at a speed of 75 m/s.
