Write an equation for the vertical displacement and find the time it takes the rock to hit the ground. 2. Write an equation for the horizontal displacement and find the horizontal displacement when the rock hits the ground. 3. Write an equation for the vertical velocity and find the vertical velocity just before the rock hits the ground. In this problem, earth's gravitational acceleration has been approximated with 10 m/s/s. An object is thrown with a 40 m/s upward vertical velocity and a 30 m/s horizontal velocity. 4. Find the time it takes for the object to reach the top of its path. 5. Write an equation for the vertical displacement and find the vertical displacement when the object is at the top. 6. Write an equation for the horizontal displacement and find the horizontal displacement when the object is at the top. 7. You throw an object from the top of a 50 m high building. The object leaves your hand with a speed of zero in the vertical and 10 m/s in the horizontal. How far from the base of the building will the object hit the ground below. Assume the ground is horizontal and air resistance is not important.
