A rock is thrown from a cliff and lands 20.2 m from the base of the cliff, and it was thrown horizontally with a speed of 12.7 m/s. a.) How tall is the cliff?
A tennis ball is hit straight up with an initial speed of 20 m/s at t = 0s. Here we define the position where the tennis ball is initially hit as y0 = 0m and upward as +y direction.
A lifeguard stands on top of a watch tower at the beach and purposely throws a stone horizontally with a speed of vi=18.0 m/s. The height of the tower is 50.0 m above the ground. With what speed does the stone land? How long after being released does the stone strike ground? With what angle of impact does the stone land?
A student launches a small rocket which starts from rest at ground level. At a height h=1.04km, the rocket reaches a speed of vf=391m/s. At that height, the rocket runs out of fuel, so there is no longer any thrust propelling it. After the rocket's engine turns off at a height of h=1.04km, it continues to move upward due to the velocity that it reached. What is the rocket's acceleration, in meters per squared second, during the period from engine shutoff until it returns to the ground? Ignore air resistance.
Sasha stands on the ground and tosses a baseball perfectly vertically up to her friend Helge, who catches it by reaching outside the window of his apartment building. She gives the ball an initial speed of vi= 19.7 m/s, and Helge catches it 1.40 s later when it reaches his hands. If Helge were to drop the baseball from rest at this point, what would be its final speed vf when it reaches Sasha’s hands down below? (She catches the ball at the same height from which she tossed it.)For your limit check, investigate what happens to vf as Sasha’s launch speed gets very large (i.e., as vi→∞). This is my question. I am also trying to figure out what formulas I would use to solve it.
A juggler performs in a room whose ceiling is 4.62 m above the level of his hands. He throws a ball upward with an upward speed of v 0 so that it just reaches the ceiling. At the instant when the first ball is at ceiling, the juggler throws a second ball upward with 4v 0 /3 velocity. At what distance above the juggler’s hand do they pass each other?
A student stands at the edge of a cliff and throws a stone horizontally over the edge with a speed of vo=18.5 m/s. the cliff is h=49.0 m above a flat, horizontal beach. what are the coordinates of the initial position of the stone and the components of the initial velocity?
You throw a ball towards a wall at speed 27 m/s and at an angle 40.0° above the horizontal. The wall is 22.4 m from the release point of the ball.
A Tennis player hits a ball 2.0 m above the ground at an angle 5º above the horizontal. The horizontal distance to the net is 7.0 m and the net is 1.0m high. What is the minimum initial speed, vi, needed to clear the net? (Hint: this is like the problem done in the handout, but since we don’t know the initial speed, we have to find horizontal and vertical components and the time symbolically and carry that through.) Im so confused and don't know where to start...

An airplane releases a ball as it flies parallel to the ground at a height of ℎ=145 m as shown in the figure. If the ball lands on the ground a horizontal distance equal to the height ℎ from the release point, calculate the speed ? of the plane. Neglect any effects due to air resistance, and use ?=9.81 m/s2 for the acceleration due to gravity.
