Question

Mrs. Fatima has a a small sports car that she uses to drop her kids off from school that has a mass of 5000 kg. Mr. Zaid drives a truck with a mass of 4200 kg. If the two vehicles are travelling down the road, side by side, at a speed of 75 km/hr, which one will have the most momentum? Explain *

Answer 1

`\textbf{Use equation of momentum}`

`p=mv`

`\text{momentum\ =\ mass x velocity}`

`\textbf{Substitute in the values}`

`5000 * 75 = 375,000 \text{\ kg\ km/hr}`

`4200 * 75 = 315,000 \text{\ kg\ km/hr}`

`\textbf{The\ small\ sports\ car\ will\ have\ the\ most\ momentum.}`
