A suspension bridge is 60.0 m above the level base of a gorge. A stone is thrown or dropped from the bridge. Neglect air resistance. Let g = 10.0 m/s2.

(a) If you drop the stone, how long does it take for it to fall to the base of the gorge?

(b) If you throw the stone straight down with a speed of 20.0 m/s, how long before it hits the ground?

(c) If you throw the stone with a velocity of 20.0 m/s at 90.0° above the horizontal, how long before it hits the ground?

(d) If you throw the stone with a velocity of 20.0 m/s at 30.0° above the horizontal, how far from the point directly below the bridge will it hit the level ground?
