Document Summary
= 3. 265 s qc since the time of 8s is more than the time of flight, the stone will be back to the ground qd s = vt 0. 5gt^2 taking upward direction as +ve plugging in, s = 16*2. 4 0. 5*9. 8*2. 4^2. Example: a stone is thrown horizontally at 15 m/s from the top of a cliff that is 44 m high. Answer the following questions assuming no friction: how long does it take the stone to reach the ground? b. G: info in part a f: the horizontal distance traveled by the stone as it falls e: dx = vx t s: dx = 15 m/s * 3 s a: dx = 45 m. The vertical velocity of the ball when going over the edge of the table is 0 m/s. The actual velocity can be found by using the pythagorean theorem: Vv = vertical velocity = 0. 98 m/s so.
