Question

A student stands at the edge of a diff and throws a stone horizontally over the edge with a speed of v, 17.5 m/s. The diff is h = 45.6 m above a body of water as shown in the figure below. (a) What are the coordinates of the initial position of the stone? (b) What are the components of the initial velocity of the stonei? m/s m/s (c) What is the appropriate analysis model for the vertical motion of the stone? O particle under constant speed O particle under constant, nonzero acceleration d) What is the appropriate analysis model for the horizontal motion of the stone? O particle under constant, nonzero acceleration O partidle under constant speed (e) Write symbolic equations for the x and y components of the velocity of the stone as a function of time. (Use the following as necessary: Vx g, and t. Indicate the direction of the velocity with the sign of your answer) (F) Wirite symbolic equations for the position of the stone as a function of time. (Use the following as necessary: Vixe g, and t. Indicate the direction of the displacement with the sign of your answer.) How long after being released does the stone strike the water below the cliff? (h) With what speed and angle of impact does the stone land? m/s counterclockwise from the x axis

Explanation / Answer

a) xi = 0 m
yi = h = 45.6 m

b) vix = 17.5 m/s

viy = 0 m/s

c) the stone was falling under the gravitational force action

so the answer is particle under constant,nonzero accelaration

d) in horizontal direction,no forces are acting so accelaration is zero,which means that particle under constant speed

according to chegg rules i answered first four questions in a problem
