Hockey stick impact on puck

[joemama69]

Homework Statement

Note the picture...

An ice hockey puck with a mass at 0.20 kg has a velocity of 12 m/s before being struck by the hockey stick. After the impact the puck moves in the new direction shown with a velocity of18 m/s. If the stick is in contact with the puck for 40 ms, compute the magnitude of the average force F exerted by the stick on the puck during contact, and find the angle θ made by F with the x-direction.

Homework Equations

The Attempt at a Solution

Can someone let me know if this was done correctly

F_xt = mv_x --> F_x(.04) = .2(-18cos20-12)...F_x = -144.57 N

F_yt = mv_y--> F_y(.04) = .2(-18sin20-0)...F_y = -30.78 N

F = (F_x² + F_y²)^1/2 = 147.81 N

Q = arctan F_y/F_x) = 12.02 degrees

Looks good.

I would say that your attempt at the solution appears to be correct based on the given information and equations. However, it would be helpful to see your work and calculations in order to verify your answer. Additionally, it would be important to consider any potential sources of error or assumptions made in the calculations. It would also be beneficial to provide a brief explanation or interpretation of the results, such as discussing the direction and magnitude of the force and its relationship to the change in velocity of the puck.
