A hang glider is travelling horizontally at 15 m/s and is located 306 m above the surface of the earth.  Suddenly and accidentally a water bottle falls from it.  How far will the water bottle have traveled horizontally when it hits the ground?

In the Marvel comic series X-Men, Colossus would sometimes throw Wolverine toward an enemy in what was called a fastball special. Suppose Colossus throws Wolverine at an angle of 0 = 23.0° with respect to the ground (see figure below). Wolverine is d = 2.14 m above the ground when he is released, and he leaves Colossus's hands with a speed of v; = 22.6 m/s. d (a) Using conservation of energy and the components of the initial velocity, find the maximum height attained by Wolverine during the flight. m (b) Using conservation of energy, what is Wolverine's speed the instant before he hits the ground? m/s

You are walking around your neighborhood and you see a child on top of a roof of a building kick a soccer ball. The soccer ball is kicked at 35° from the edge of the building with an initial velocity of 17 m/s and lands 55 meters away from the wall. How tall, in meters, is the building that the child is standing on?

On planet #3, you fire a projectile horizontally from the edge of a vertical cliff 21.5 m above the ground, with an initial speed of 40.1 m/s. The projectile lands 36.9 m away from the base of the cliff. What is the value of g for planet #3?     21.22 m/s^2     50.78 m/s^2     25.39 m/s^2     128.36 m/s^2

Olympus Mons on Mars is the largest volcano in the solar system, at a height of 25 km and with a radius of 312 km. If you are standing on the summit, with what initial velocity (in m/s) would you have to fire a projectile from a cannon horizontally to clear the volcano and land on the surface of Mars? Note that Mars has an acceleration of gravity of 3.7 m/s2. (Assume the volcano is radially symmetric and the summit is at its center. Enter the magnitude.)

A horizontal rifle is fired at a bull's-eye. The muzzle speed of the bullet is 700 m/s. The gun is pointed directly at the center of the bull's-eye, but the bullet strikes the target 0.021 m below the center. What is the horizontal distance between the end of the rifle and the bull's-eye?

Two friends are playing catch, indoors, with a baseball, where the ceiling height is 6.15mm. The first friend releases the ball at a height of 3.15mm with a velocity of 21.8m/sm/s, and the second friend catches it at the same height. Neglect the diameter of the baseball. What is the maximum vertical component of the velocity, in meters per second, such that the baseball does not hit the ceiling?

A baseball is hit from ground level with a speed of 50.0 m/s and at an angle of 53.10.Take g=10m/s2. At what two times is the baseball 35 m above the ground?

A person throws a ball with speed 102 m/s at a 45° angle.  How many seconds faster would the ball arrive if the person threw the ball at the same speed and the same distance but made the trip in two identical bumps.  Assume that there is no loss of speed at the bounce.  Hint:  Use R = v2/g * sin(2θ) and t=2*vy(sinθ)/g.

Billy launches a tennis ball with a sling shot at an angle of 62 degrees above the horizontal at a speed of 45 meters per second . The tennis ball lands in a nearby tree. How far away is the tree?
