A stone is thrown upward from a cliff at an angle of 35 degrees above the horizontal with a speed of 47 m/s. The stone hits the ground 5.0 s later. a) What is the x component of the stones initial velocity?

An inflatable raft (unoccupied) floats down a river at an approximately constant speed of 5.2 m/s. A child on a bridge, 82 m above the river, sees the raft in the river below and attempts to drop a small stone onto the raft. The child releases the stone from rest. In order for the stone to hit the raft, what must be the horizontal distance between the raft and the bridge when the child releases the stone? m

A student standing on a cliff that is a vertical height d = 8.0 m above the level ground throws a stone with velocity v0 = 23 m/s at an angle θ = 16 ° below horizontal. The stone moves without air resistance; use a Cartesian coordinate system with the origin at the stone's initial position. A) With what speed, vf in meters per second, does the stone strike the ground?  B)  If the stone had been thrown from the clifftop with the same initial speed and the same angle, but above the horizontal, would its impact velocity be different?   If the stone had been thrown from the clifftop with the same initial speed and the same angle, but above the horizontal, would its impact velocity be different?

You throw a ball from the ground level at an angle of 0 = 40.0° above the horizontal. The ball lands on top of a cliff that has a height of h=10.0 m. When you release the ball, it is traveling at a speed of 25.0 m/s. How long does it take for the ball to land on top of the cliff?
