a person pushes on a hockey puck with their stick at an angle so the vertical force is 22N down and the horizontal force is 45N forward. Assume the ice is frictionless.
What is the actual force the hockey player transmits to the puck?
what is the work done by the person pushing the hockey stick if they push the puck for 3 seconds as it moves with a constant velocity of 22m/s forward?

Please help I don't know how to start this question

1. a. X = 45 N.
Y = -22 N.

F^2 = 45^2 + (-22)^2 = 2,509
F = 50.09 N.

b. d = 22m/s * 3s = 66 m.

Work = F*d = 50.09 * 66 = 3306 Joules.
