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
