A rock is thrown from the edge of the top of a 5 m tall building at angle of 45° above the horizontal. The rock strikes the ground a horizontal distance of 8 m from the base of the building. Assume that the ground is level and that the side of the building is vertical. Determine the speed with which the rock was throw

A 2kg rock is thrown horizontally from the top of a building that is 20m high. The rock’s initial horizontal velocity is 5m/s. When the rock is halfway to the ground, what is the net force on it (including direction)? How long did it take for the rock in problem 1 to hit the ground? How far from the base of the building did the rock in problem 1 hits？

A 700 gram ball is thrown from the top of a 25 meter tall building. The ball is thrown with an initial speed of 10 m/s at an angle 30 degrees above the horizontal. For our conservation of energy calculations, we will choose the Ball + Earth as our system and use the ground as h = 0. The kinetic energy of the ball when it is thrown = J. When the ball reaches its highest point the kinetic energy is...

A baseball is thrown from the roof of 23.5 m -tall building with an initial velocity of magnitude 10.5 m/s and directed at an angle of 52.4° above the horizontal. What is the speed of the ball just before it strikes the ground? Use energy methods and ignore air resistance. What is the answer if the initial velocity is at an angle of 52.4° below the horizontal? If the effects of air resistance are included, will part (a) or (b)...
