Question
A $91 \mathrm{~kg}$ man lying on a surface of negligible friction shoves a 68 g stone away from himself, giving it a speed of $4.0 \mathrm{~m} / \mathrm{s}$. What speed does the man acquire as a result?
Step 1
First, we need to find the momentum of the stone after it is shoved. Momentum is given by the formula: momentum = mass × velocity. Show more…
