Question

What velocity must a car with a mass of 1110 kg have in order to have the same momentum as a 2280 kg pickup truck traveling at 24 m/s to the east? Answer in units of m/s.

Answer 1

Answer:

49.3 m/s

Explanation:

The momentum is defined as the product of the object velocity and its mass.

So the momentum of the truck is

$P_t = 2280 * 24 = 54720 kgm/s$

For the car to have the same momentum, its speed must be

$v_c = P_t/m_c = 54720 / 1110 = 49.3 m/s$
