A basketball player is shooting some hoops, on one particular shot the ball leaves her hands 10.7m horizonally away from the hoop, and 2m vertically off the ground. Let's say she shoots a particular shot with a velocity of 10m/s at an angle of 62.8° with respect to the vertical (Assume no air resistance)
Part A) Find the horizontal and vertical components of the angled velocity vector.
Part B) Find the time it takes the ball to reach the hoop.
Part C) Assuming she makes her basket find the height of the hoop
