## Homework Statement

A resting 164 g hockey puck is hit with a force of 15.3N. The frictional force slowing the puck down is 0.75N.

a) Find the net forces acting on the puck. Remember to consider both horizontal and vertical forces

b) If the puck leaves the stick with a velocity of 45m/s how far will the puck travel in 3.0s?

m= 0.164kg

F[itex]_{applied}[/itex]= 15.3N [forward]

F[itex]_{f}[/itex]= 0.75N [backwards]

## Homework Equations

For part b = a=2(d)/t²

## The Attempt at a Solution

a- 15.3[forward] - 0.75 [backwards]

= 14.55N [forward]

The puck would have a net force of 14.55N.

(it doesn't seem right because the questions is telling me to remember the vertical forces as well.)

b- a=2(d)/t²

45m/s = 2(d)/3²

45m/s x 9 = 2(d)/9 x 9

405 m = 18(d)

22.5 m = d

Would that be correct?? It just seems off.
