Just need questions C and D answered. Thanks
A student stands at the edge of a cliff and throws a stone horizontally over the edge with a speed of
The cliff is h = 56.0 m above a flat, horizontal beach as shown in the figure.
| x0 | = | 0 m |
| y0 | = | 56.0 m |
(b) What are the components of the initial velocity?
| v0x | = | 19.5 m/s |
| v0y | = | 0 m/s |
(c) Write the equations for the x- and y-components of the velocity of the stone with time. (Use the following as necessary: t. Let the variable t be measured in seconds. Do not include units in your answer.)
| vx | = |

(d) Write the equations for the position of the stone with time, using the coordinates in the figure. (Use the following as necessary: t. Let the variable t be measured in seconds. Do not state units in your answer.)
| x | = |

(e) How long after being released does the stone strike the beach below the cliff?
3.38 s
(f) With what speed and angle of impact does the stone land?

= | 38.47 m/s |
| ? | = | 59.94 ° below the horizontal |
Initial position , x0 = 0 m , y0=56.0 m
Initial velocity components , v0x = 19.5 m/s , v0y = 0 m/s
To find = a) components of velocity
b) components of position
