An object is thrown vertically upward with a velocity of 30m/s on the surface of the moon. If the gravity on the surface of the moon is 2m/s2 , calculate the heights and velocities of the object at 5 sec, 10 sec, 15 sec, 20 sec, 25 sec & 30 sec after the ball was thrown. Now show graphically how the distances and velocities of the object change with respect to time.

A ball is thrown from a rooftop with an initial downward velocity of magnitude v0 = 1.1 m/s. The rooftop is a distance above the ground, h = 46 m.

A ball is thrown from a rooftop with an initial downward velocity of magnitude v0 = 1.1 m/s. The rooftop is a distance above the ground, h = 46 m. In this problem use a coordinate system in which upwards is positive. Part (a) Find the vertical component of the velocity, Vfy, in meters per second, with which the ball hits the ground. Part (b) If we wanted the ball's final speed to be exactly 27.3 m/s from what height, hnew (in...

A ball is thrown straight downward from the top of a building. Its initial velocity is 12 m/s downward. It hits the ground 1.2s after release. How tall is the building? *ignoring any air resistance* Please explain in detail why you need to solve for vf first using Vf=Vo+at and then plug Vf into Vf^2=Vo^2+2a(x2-x1) I assumed that since the ball hits the ground that vf=0m/s but using that I am getting the incorrect answer of 7.3m instead of the correct...
