Evaluate this claim by calculating the maximum height that such a jump would attain.?

Question

Michael Jordan, formerly of the Chicago Bulls basketball team, has some fanatic fans. They claim that he is able to jump and remain in the air for two full seconds from launch to landing. Evaluate this claim by calculating the maximum height that such a jump would attain. For comparison, Jordan's maximum height has been estimated at about one meter.

Thank you both soOo much!!

Answer 1

since it takes 2 second to land, that means it only takes 1 second to reach the maximum height.

find the inital velocity
Vf= at+Vi
0 = (-9.8)(1) + Vi
Vi = 9.8m/s

x = 1/2at^2 + Vt
x = 1/2(-9.8)(1)^2 + (9.8)(1)
x = 4.9m

Answer 2

Use the equation t=sqrt(2h/g), where t is time, h is height and g is 9.8.

1=sqrt(2h/9.8)
1=2h/9.8
h=4.9 m
