Question

A hockey puck of mass 150 g is sliding south along the ice and slows at a rate of 1.2 m/s². What is the net force acting on the puck?

Answer 1

Answer:

0.18 N or 180 N

Explanation:

Mass,m = 150g

acceleration,a = 1.2m/s2

CHANGE FROM g TO kg

1kg =1000g

so 150g =150/1000 = 0.15kg

But Force, F = mass,m × acceleration,a

F=ma

F=0.15×1.2

F= 0.18 N
