Question

A place-kicker 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 24.0 m/s at an angle of 49.0° to the horizontal. By how much does the ball clear or fall short (vertically) of clearing the crossbar? (Enter a negative answer if it falls short.)

Step 1

6 \times \sin(48^\circ)\), and \(a = -9.8\): \(0 = 23.6 \times \sin(48^\circ) - 9.8t\) \(t = \frac{23.6 \times \sin(48^\circ)}{9.8}\) \(t \approx 1.78\) seconds Show more…
