Reference no: EM13558213

A suspension bridge is 60.0 m above the level base of a gorge. A stone is thrown or dropped from the bridge. At the location of the bridge, g has been measuredto be 9.83 m/s². In each of the following, assume that there is no air resistance.

(a) If you drop the stone, how long does it take for it tofall to the base of the gorge?
(b) If you throw the stone straight down with a speed of18.0 m/s, how long before it hits the ground?
(c) If you throw the stone with a velocity of 18.0 m/s at 35.0° abovethe horizontal, how far from the point directly below the bridge will it hit the level ground?
