Question

A bush cricket jumps from the ground into the air with an initial vertical velocity of 4 feet per second. Write an equation that gives the cricket’s height (in feet) as a function of the time (in seconds) since it left the ground. After how many seconds is the cricket 3 inches off the ground? Does the cricket jump higher than 3 inches?

Answer 1

h = -1/2 g t^2 Vo t + Ho

g is gravitational acceleration ... 32 ft/s^2

Vo is initial velocity .. 4 ft/s

Ho is initial height ... 0
