Here is a problem I am having difficulty with:(adsbygoogle = window.adsbygoogle || []).push({});

In attempting to pass the puck to a teammate, a hockey player gives it an initial speed of 2.89 m/s. However, this speed is inadequate to compensate for the kinetic friction between the puck and the ice. As a result, the puck travels only one-half the distance between the players before sliding to a halt. What minimum initial speed should the puck have been given so that it reached the teammate, assuming that the same force of kinetic friction acted on the puck everywhere between the two players?

What we know:

Vo = 2.89 m/s <---- this speed only derives half of the expected result

fk angle is Cos 180 = -1, which is the direction of the force acting on the puck.

I am completely confused as to where to begin here.

Any help would be appreciated.

Thanks,

Matt
