The cannon on a battleship can fire a shell a maximum distance of 32.0 km. (a) Calculate the initial velocity of the shell. (b) What maximum height does it reach? (At its highest, the shell is above 60% of the atmosphere—but air resistance is not really negligible as assumed to make this problem easier.) (c) The ocean is not flat, because the Earth is curved. Assume that the radius of the Earth is 6.37103 km. How many meters lower will its surface be 32.0 km from the ship along a horizontal line parallel to the surface at the ship? Does your answer imply that error introduced by the assumption of a flat Earth in projectile motion is significant here?
A ball is thrown with an initial horizontal velocity of 30m/s from the height of 3m above the ground. And 40m from a vertical wall. How far from the wall will the ball rebound from the first time?
On the moon, the gravitational acceleration is 1/6 x g of Earth. If you shoot a golf ball on the moon with a launch angle of 25 degrees and an initial velocity of 22 m/s, how high is its peak height? How many times higher did it go than it would have on Earth?
If a baseball player can throw a ball a maximum distance of 200 ft over the ground. What is the maximum vertical height to which he can throw it? Assume the ball to have the same initial speed in each case. A. 40 ft C. 60 ft B. 25 ft D. 50 ft
Can you help me with this question? A motocyclist drives his bike off of a 12 m high horizontal ledge. If he is driving at a speed of 22 m/s horizontally, how far from the base of the ledge does he land?
The free throw line in basketball is 4.57 m (15 ft) from the basket, which is 3.05 m (10 ft) above the floor. A player standing on the free throw line throws the ball with an initial speed of 8.15 m/s, releasing it at a height of 2.44 m (8 ft) above the floor. At what angle above the horizontal must the ball be thrown to exactly hit the basket? Note that most players will use a large initial angle rather than a flat shot because it allows for a larger margin of error. Explicitly show how you follow the steps involved in solving projectile motion problems.

(Select all that apply.) The error could be significant compared to the size of a target. The error is significant compared to the distance of travel. The error is insignificant compared to the distance of travel. The error is insignificant compared to the size of a target.
If a baseball is hit with a vertical speed of 30 m/s and a horizontal speed of 2 m/s, how long will the ball remain in the air? (Assume for the purposes of this question that the ball starts at nearly ground level.) How far will it go?
If Emily throws the ball at an angle of 30∘ below the horizontal with a speed of 14m/s, how far from the base of the dorm should Allison stand to catch the ball? Assume the vertical distance between where Emily releases the ball and Allison catches it is 6.0m.
A golf ball is hit by a club off of a tee with a velocity of 15.0 m/s at 50.0 degrees above the horizontal. The hole (or cup) is on a green (flat level ground) that is 2.75 m above the tee where the golf ball was driven. The golf ball hits the green on its way down from its maximum height. (a) What is the maximum height above the tee that the ball reached on its way to the green? (b) What is the velocity of the ball just before it hits the green? (c) Include a complete diagram of the situation
