By energy conservation, the change in gravitational potential is same for both, thus, change in kinetic energy is also the same which in turn implies same final speed if initial is same.(Note that masses will cancel out)

A student stands at the edge of a cliff and throws a stone horlzontally over the edge with a speed of vi = 21.5 m/s. The cliff Is h = 50.3 m above a body of water as shown in the figure below. (a) What are the coordinates of the initial position of the stone? (Note that the origin is at the base of the cliff, where the x- and y-axes intersect.)(b) What are the components of the initial velocity of...

NAME: Problem 1. (40 pts) A stone is dropped into a river from a bridge that i ove the water (with zero initial velocity). Another stone is thrown at an angle of 45° below the horizontal exactly 1 (one) second after the first with some initial velocity. As it turns out the two stones hit the water at exactly the same moment. (Hint: after means shorter time.) a) (20 pts) What is the initial velocity of the second stone? b)...
A person on a cliff throws a ball with an initial velocity of 30.2 m/s at an angle of 46.50 above the horizontal. If the initial height of the ball, compared to it impact location is, Y = 18.5 m, what is the maximum height it obtains, and where does it land?

A ball with an initial velocity of 11.5 m/s and mass 1.9 kg moves at an angle 65.5° above the horizontal. The ball hits a vertical wall and bounces off so that it is moving 65.5° above the horizontal, moving in the opposite direction with the same speed. See the figure. What was the magnitude of the impulse delivered by the wall, in kilogram meters per second?
