A stone is thrown vertically down at a speed of 10 m / s from the top of a building 45 meters high. (a) Determine the speed of the stone the instant it hits the ground. (b) How long does it take to fall?
(4 points) A stone is thrown from a rooftop at time t=0 seconds. Its position at time t is given by r(t) = 4ti — 2tj + (24.5 – 4.912) k. The origin is at the base of the building, which is standing on flat ground. Distance is measured in meters. The vector i points east, j points north, and k points up. (a) How high is the rooftop? meters. (b) When does the stone hit the ground? seconds. (the...
