A basketball leaves a player's hands at a height of 2.10metres above the floor. The basket is 2.60metres above the floor. The player likes to shoot the ball at a 38 degree angle. If the shot is made from a horizontal distance of 11.00metres and must be accurate to +/-0.22metres (horizontally), what is the range of initial speeds allowed to make the basket?
I really have no idea how to do this... :(
