Question
A student stands at the edge of a and a stone horizontally over edge with a speed off v^vector_0 = 17.5 m/s. The is h = 60.0 m above a flat, horizontal beach as shown in the figure. (a) what are the coordinates of the initial position of the stone? X_0 = __________ m gamma_0 = ________ m (b) What are the components of the initial velocity? = __________m/s = _________ 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) = _________ = ________ (d) write the equations for the position of the stone using the coordinates in the figure. (Use the following as necessary: middotLet the variable t be measured in seconds. Do not state units in your answer e) How long after being released does the stone strike the beach below the ? ____________Explanation / Answer
(A) x0 = 0
y0 = 60 m
(B) v0x = 17.5 m/s
v0y = 0
(C) vx = v0x
vy = v0y + ay t = v0y - g t
(d) x = x0 + v0x t
y = y0 + v0y t - g t^2 /2
(e) it will hit the ground when y = 0
0 = 60 + 0 - 9.8 t^2 /2
t = 3.50 sec
