What speed does a hockey puck go towards the goal at a constant force of 29.5?

Posted on March 1, 2010 by admin

A hockey puck has a mass of 0.103 kg and is at rest. A hockey player makes a shot, exerting a constant force of 29.5 N on the puck for 0.16 s. With what speed does it head toward the goal?

Put answer in m/s

I won’t give you the answer but here is how you solve it:

To get velocity you need to know the acceleration and the time it was accelerating

v = a*t

You have to calculate acceleration based on the Force and the mass of the puck (in grams!)

a = F/m

so, the first equation becomes:

v = (F/m)*t

Plug the numbers into your calculator and you’ll get the answer
