A hockey player shoots hockey puck towards net. The net is 20 metres infront of the player. If the puck leaves hockey stick at 30 m/s and 10° above ice. Find x and y components of the velocity. If the goalies catches puck just infront of net calculate final velocity of the puck with magnitude and direction included in answer.

2. Relevant equations

v_{x}= vcosθ

v_{1y}=vcosθ

3. The attempt at a solution[/b

Ok now for the first I assume it means find x and y components of the velocity means of the initial velocity.

so I did the above equations of

v_{x}= vcosθ

v_{1y}=vcosθ

and got: v_{1y}=5.2 m/s

and v_{x}=29.5 m/s

now for next part I did:

d_{x}=v_{x}(t)

20=29.5(t)

t=0.7 sec

v_{2y}=v_{1y}+(g)(t)

v_{2y}=5.2+(9.81)(0.7)

v_{2y}=12.1 m/s

v_{2}=√ 29.5^{2}+12.1^{2}

v_{2}=31.9 m/s

tan^{-1}(12.1/29.5)=θ

θ=22.3°

final velocity of the puck is 31.9 m/s [22.3° Forward]

Im just wondering if I did this question correctly and if my direction is correct for the final part.
