A hockey puck comes to a slow stop on the ice. The mass of the puck is 0.5 kg and the force of friction between the puck and the ice is 2.3 N. What is the acceleration of the puck?

Question

Quizplus · Accepted Answer

The formula to find the required force is: F = ma where F = Force m = mass (in kg) a = acceleration (in m/s²) To find the acceleration of an object we must isolate acceleration. To do this, we divide both sides by the mass: F = ma F/m = ma/m F/m = a Then we plug in the numbers from the problem. 2.3 N / 0.5 kg = 4.6 m/s² We know that this force is negative because the puck is slowing down.
