Question

A hockey puck with a mass of 0.16 kg is slapped so that its velocity is 50 m/sec. It slides 40 meters across the ice before coming to rest. How much work is done by friction on the puck?

Answer 1

The answer for Work done is 64J or 64Nm

Step-by-step explanation:

W=F×D

F=ma

F=mg

F=0.16×10=1.6N

W=F×D

W=1.6×40

W=64J or 64Nm
