A student stands at the edge of a cliff and throws a stonehorizontally over the edge with a speed of 27 m/s. The cliff is 53 mabove a flat, horizontal beach as shown in the figure below.
What are the coordinates of the initial position of the stone?What are the components of the initial velocity?Write the equations for the velocity of the stone with time.(Use g for the acceleration of gravity, and t as necessary.)Write the equations for the position of the stone with time.(Use g for the acceleration of gravity, and t as necessary.)How long after being released does the stone strike the beachbelow the cliff?With what speed and angle of impact does the stone land?
