A golfer hits a ball with an initial speed of 30.0 m/s at an angle of 50.0oabove the horizontal. The ball lands on a green that is 5.00 m above the level where the ball was struck. a) How long is the ball in the air? b) How far has the ball traveled in the horizontal direction when it lands? c) What is the speed and direction of motion of the ball just before it lands?

At serve, a tennis player aims to hit the ball horizontally (Figure 1).   What minimum speed is required for the ball to clear the 0.90-mm-high net about 15.0 mm from the server if the ball is "launched" from a height of hhh = 2.30 mm ? Express your answer to three significant figures and include the appropriate units.

Top Golf is a famous and well-known place for sports entertainment and family fun. Typically a building has two to three floors full of rooms for people to rent and relax in while they hit golf balls onto a 250-yard field. Suppose a person hits a golf ball from the second floor (h) with an initial velocity of 118 mph at a 15° angle (0). The golf ball is in the air for (t) secs and lands 170 (x) yards from its initial place. The path of the golf ball is depicted in figure 2. Hint: 1 mile 5280 ft, 1 yard = 3 ft = (i) How long does it take for the golf ball to land on the field in seconds? (t) (ii) At what height was the ball struck at in feet? (h) (iii) What is the maximum height the golf ball reaches in feet? (yax) Figure 2. V₂

A cannon is launched from the top of a 10m high cliff at an initial speed of 50 m/s at a 55 degree angle with the horizontal. a) Assuming the cannon lands on the ground, how long will it remain airborne?
