Question

1. a 100 kg car drives along a city street at 13.4 m/s. what is the magnitude of the cars momentum? (a) 0.0134 kgm/s (b) 74.62 kgm/s (c) 13,400 kgm/s (d) none of the above

Explanation:

Step1: Recall momentum formula

The formula for momentum is $p = mv$, where $p$ is momentum, $m$ is mass and $v$ is velocity.

Step2: Substitute given values

Given $m = 100\ kg$ and $v=13.4\ m/s$. Then $p=(100\ kg)\times(13.4\ m/s)$.

Step3: Calculate momentum

$p = 1340\ kg\cdot m/s$.

Answer:

D. none of the above
