You throw a stone vertically upward from the roof of an 56 m tall building with a velocity of 59 m/s. how long after the stone will land the ground? [assume g= 10m/s2. (round calculations to the fourth decimal place)

Ablue car pulls away from a red stop-light just after it has turned green with a constant acceleration of 0.5 m/s 2 . a green car arrives at the position of the stop-light 6.5 s after the light had turned green. if t = 0 when the light turns green, at what time does the green car catch the blue car if the green car maintains the slowest constant speed necessary to catch up to the blue car? answer in units of s.
