Textbook Problem

A student stands at the edge of a cliff and throws a stone horizontally over the edge with a speed of vi = 18.0 m/s. The cliff is h = 50.0 m above a body of water as shown in Figure P4.13. (a) What are the coordinates of the initial position of the stone? (b) What are the components of the initial velocity of the stone? (c) What is the appropriate analysis model for the vertical motion of the stone? (d) What is the appropriate analysis model for the horizontal motion of the stone? (e) Write symbolic equations for the x and y components of the velocity of the stone as a function of time. (f) Write symbolic equations for the position of the stone as a function of time. (g) 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?

A student stands at the edge of a cliff and throws a stone horizontally over the edge with a speed of vi=18.0 m/s. The cliff is h=50.0 m above a body of water as shown in the figure.

(a) What are the coordinates of the initial position of the stone?

(b) What are the components of the initial velocity of the stone?

(c) What is the appropriate analysis model for the vertical motion of the stone?

(d) What is the appropriate analysis model for the horizontal motion of the stone?

(e) Write symbolic equations for the x and y components of the velocity of the stone as a function of time.

(f) Write symbolic equations for the position of the stone as a function of time.

(g) How long after being released does the stone strike the water below the cliff?

(h) With what speed and angle of impact do the stone land?

A student stands at the edge of a cliff and throws a stonehorizontally over the edge with a speed of vi = 18.2 m/s. The cliffis h = 49.5 m above a body of water as shown in the figurebelow.

(a) What are the coordinates of the initial position of the stone?(Do not assume that the student is the point of origin.)

(b) What are the components of the initial velocity of thestone?


(c) What is the appropriate analysis model for the vertical motionof the stone? (Select all that apply.)
