Answer to Question #263863 in Physics for Claude

Question

In a pandayan (foundry), a pot made of cast iron slid and came to a complete stop atop a surface also made of cast iron. The pot was quite heavy (m= 2.5 kg) and had an acceleration of 4.5 m/s². Calculate the frictional force that stopped the pot. (Hint: Since the pot was originally sliding, the frictional force involved is kinetic friction.]

Answer 1

$F_{fr}=ma=2.5\cdot4.5=11.25\ (N)$
