Question

a skateboarder with a total mass of 60 kg is moving at 5.0 m/s along a sidewalk when a rock suddenly stops the wheels of the skateboard. what is the momentum of the skateboarder as he flies of the front of the board? formula: $p = m \times v$ 300 kg·m/s 30 kg·m/s 12 kg·m/s 1.2 kg·m/s

Explanation:

Step1: Identify given values

Mass $m = 60\ \text{kg}$, velocity $v = 5.0\ \text{m/s}$

Step2: Apply momentum formula

Use $P = m \times v$
$P = 60\ \text{kg} \times 5.0\ \text{m/s}$

Answer:

300 kg·m/s
