Chapter 4, Problem 4.23P
A placekicker must kick a football from a point 36.0 m (about 40 yards) from the goal. Hall the crowd hopes he 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?

To celebrate her good performance on a physics test, Alice decides to break out a bottle of champagne. In order to avoid property damage, she takes the bottle outside to uncork it. The cork pops off the champagne bottle with a velocity of 12.0 m/s at an angle of 15° relative to the vertical. When the cork is released, Alice is holding the bottle such that the cork is 1.80 m above the ground. How far does Alice have to walk to retrieve the cork?
In a circus, a “human cannonball” is launched from a cannon and lands in a net. The cannon releases him at the same height as the net. His initial velocity is 18.3 m/s in a direction 40.0° above the horizontal.

b) How far does he travel horizontally?
c) What is the velocity upon impact?
The circus manager from the previous question wants to make the stunt more dramatic by firing the stuntman through a hoop 9.0 m high then land in a safety net at the same height as the cannon. The cannon’s angle is changed to 45.0° and the velocity is increased to
21.0 m/s. The manager needs to know where to place the hoop and safety net.

- For all questions, assume concepts such as friction or air resistance are negligible, unless stated otherwise in the question. A ball is launched from ground level at an angle of 60˚ and with a speed of 15 m/s. a)What is the maximum height the ball will reach? b)How far horizontally will the ball travel before returning to ground level?arrow_forwardProfessional golfers can drive the ball over 200 m. While air resistance is significant, its effects are nearly canceled because lift is gained from backspin on the ball, and so a reasonable description of the ball’s trajectory is obtained if air resistance is neglected. Suppose a golfer hits a ball 200 m on level ground, giving it an initial velocity at an angle of 45o.

By how much does it clear it/miss clearing it? Where does ball reach max height? The back line of the court on the receiving side is 19 meters away from where the server strikes the ball.
