QUESTION:

In the text, we calculated the range for a projectile that lands at the same elevation from which it is fired as . A golf ball hit from an elevated tee at 45.0 m/s and an angle of 35.0 lands on a green 20.0 m below the tee (Figure 3-37). (Ignore any effects due to air resistance.) (a) Calculate the range using the equation even though the ball is hit from an elevated tee. (b) Show that the range for the more general problem (Figure 3-37) is given by where y is the height of the green above the tee. That is, y__h. (c) Compute the range using this formula. What is the percentage error in neglecting the elevation of the green?
