a 30 kg child sleds to the right at 5.3 m/s. what is their momentum? p = ? kg · m/s round your answer to the nearest tenth. remember: p = m · v enter the sign (+ or -) and the magnitude.
Answer
# Explanation:
## Step1: Identify given values
$m = 30$ kg, $v=5.3$ m/s
## Step2: Apply momentum formula
$p = m\times v=30\times5.3$
$p = 159.0$ kg·m/s
Since the child is moving to the right, the sign is +.
# Answer:
+ 159.0 kg·m/s
