**Another Hard Physics Question now with attempt**
A placekicker must kick a football from a point 36.0 m (about 39.0 yd) from the goal, and the ball must clear the crossbar, which is 3.05 m high. When kicked, the ball leaves the ground with a velocity of 21.2 m/s at an angle of 45.0° to the horizontal.
By how much does the ball clear or fall short of clearing the crossbar?
Any help is appreciated. Thanks so much.
Well, first I found out that the ball does clear the crossbar. . . but I am trying to once again do the components with the angles and finding the hypotenuse of the vectors. But, this might be completely wrong. Help please?
