Concept explainers
A placekicker must kick a football from a point 36.0 m (about 40 yards) from the goal. 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 20.0 m/s at an angle of 53.0° to the horizontal, (a) By how much does the ball clear or fall short of clearing the crossbar? (b) Does the ball approach the crossbar while still rising or while falling?

We denote the initial horizontal position of the football by xo and its initial x- component of velocity by vox. For the position in the horizontal directional direction in terms of time t, we x=xo+voxt. Solving for t gives the following equation= t=x-xo\voxarrow_forwardA placekicker is about to kick a field goal. The ball is 20.4 m from the goalpost. The ball is kicked with an initial velocity of 23.4 m/s at an angle above the ground. Between what two angles, 8₁ and ₂, will the ball clear the 2.57-m-high crossbar? Give your answers as (a) the smaller angle and (b) the larger angle. (Hint: The following trigonometric identities may be useful: sec 0-1/(cos) and sec²0-1+tan²8.)
