2. A placekicker must kick a football from a point 36 m from the goal, and half the crowd hopes the ball will clear the crossbar, which is 3.05 m high. When kicked, the ball leaves the ground with a speed of 20 m/s al an angle of 53° to the horizontal. (a) By how much does the ball clear or fall short of clearing the crossbar? (b) Does the approach the crossbar while still rising or while falling? First try to solve this problem on a blank sheet of paper without extra hints. Only later fill in the answers in the space provided on the other side of this sheet. lf you have no clue what to do, you will find hints on the other side. = 20m, Lin 94 3 S = 34m Ay-h = 3.4 -30523, 95 m Z . o28 Zea 134 Mm b) Ty 20 m findd — Gs 3s = 14 .
