1. A Liberty hockey player slaps the puck due north at a velocity of 27 m/s. He is playing outside and has an east wind affecting the puck which has a magnitude of 12m/s. What will the direction of the puck be in degrees and what will be its velocity?
2. Determine the vertical and horizontal components of (a) a shot putter's throw which is at an angle of 45 deg to the horizontal at a velocity of 9 m/s, and (b) a basketball player whose free throw leaves his hand at an angle of 60 deg. at a velocity of 7 m/s.
3. What would be the vertical and horizontal components of a swimmer who leaves the block at an angle of 40 deg. at a velocity of 3.3 m/s? Is there an angle of takeoff that would be better than this?
