Question 1163910: A grasshopper jumps straight up with a intial velcoity of 14m/s
a) what will be the velocity of the grasshopper 1.0 second afer it left the ground
b) at what time will the grashoppers velocity reach 0m/s Answer by ikleyn(52778) (Show Source):
If forget/neglect the air resistance and consider the events in vacuum,
where only gravitation does matter, then
(a) v = - g*t = 14 - 10*1 = 4 m/s
(here g is the free fall acceleration 9.81 m/s ~ 10 m/s).
(b) t = = = 1.4 seconds.
