Question 29





Q29: A student stands at the edge of a cliff and throws a stone horizontally over the edge with a speed of vi = m/s. The cliff is h = m above a body of water as shown in Fig- ure P4.29.
(a) What are the coordinates of the ini- tial position of the stone?
(b) What are the compo- nents 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?
