Question
A rock is thrown, from the edge of a building of height h (with respect to the ground), vertically upwards with a speed V1a = 10.0 m/s. On its way down, the rock just slides off the edge of the building and continues to fall until it reaches a speed V1b = 20.0 m/s just before hitting the ground.
(a) What is the height h of the building?
(b) What is the maximum height that the rock reaches?
(c) What is the rock's flight time from when it is thrown until it reaches the ground?
(d) If at the instant the first rock is thrown,
Another rock is thrown vertically up from the ground with a speed V2a = 20.0 m/s, how high would the rocks reach?

- A ball is dropped (from rest) from a window and hits the ground with a speed of 7.0m/s. If the ball were dropped from double the height, what would be its speed (in m/s) when it hits the ground? Your Answer:arrow_forwardA student stands at the edge of a cliff and throws a stone horizontally over the edge with a speed of v 20.5 m/s. The cliff is h = 26.0 m above a flat, horizontal beach as shown in the figure. (a) What are the coordinates of the initial position of the stone? Xo = m Yo- m (b) What are the components of the initial velocity? m/s m/s Vox= Voy in seconds.

- 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.arrow_forwardA physics student throws a ball upward at 19.6 m/s from a window 58.8 m above the ground (A) How high will the ball go above the window?
