A golfer imparts a speed of 30.3 m/s to a ball, and it travels the maximum possible distance before landing on the green. The tee and the green are at the same elevation. (a) How much time does the ball spend in the air? (b) What is the longest "hole in one" that the golfer can make, if the ball does not roll when it hits the green?

A golfer gives a ball a maximum initial speed of 34.4 m/s. (a) What is the longest possible hole-in-one shot for this golfer? Neglect any distance the ball might roll on the green and assume that the tee and the green are at the same level. (b) What is the minimum speed of the ball during this hole-in-one shot?

A volleyball is spiked so that it has an initial velocity of 15 m/s directed downward at an angle of

$$55^\circ$$

below the horizontal. What is the horizontal component of the ball's velocity when the opposing player fields the ball?

As a tennis ball is struck, it departs from the racket horizontally with a speed of 28.0 mis. The ball hits the court at a horizontal distance of 19.6 m from the racket. How far above the court is the tennis ball when it leaves the racket?

A skateboarder shoots off a ramp with a velocity of 6.6 $\mathrm{m} / \mathrm{s}$, directed at an angle of $58^{\circ}$ above the horizontal. The end of the ramp is 1.2 m above the ground. Let the x axis be parallel to the ground, the +y direction be vertically upward, and take as the origin the point on the ground directly below the top of the ramp. (a) How high above the ground is the highest point that the skateboarder reaches? (b) When the skateboarder reaches the highest point , how far is this point horizontally from the end of the ramp ?
