Question:

A golfer strikes a golf ball at an an angle of 17 degree above the horizontal. With what velocity must the ball be struck in order to reach the green, which is a horizontal distance of 250 from the golfer at the same height.

The answer should be66m/s 17 degree above the horizontal

I know that the range is given which is 250 m and we also know the angle it means the velocity has x and y components.

I think that height dy should be zero because the ball starts its motion and comes back to the same point . so shouldn't it b zero ??

I don't know how to approach to the answer. plz give me some help.

Thanks
