[SOLVED] The Flea
A flea, jumping with its highest possible initial speed, can jump to a maximum vertical height of 1 cm. What is
the time spent in the air by the flea during the vertical jump? What would be the time spent in the air if the flea
were instead to leave the ground at an angle of 45° to the horizontal? What is the maximum horizontal distance
it can jump? Answer: 0.09 s, 0.063 s, 0.0196 m
d=V2t-(1/2)at
a)d=0.01m, a=g, v2=0
d=V2t-(1/2)at
0.01=-4.9t^2
t=0.045s *2
t=0.09s
b) tried finding initial velocity from part 1
