You throw a ball straight into the air from a height of 4 feet and with a speed of 5.3 m/s. The moment the ball leaves your hand you start running away at a speed of 2.37 m/s. How far are you from the ball, the moment it hits the ground?

Answer 1

4 feet =1.2192meters
(type **** 4 feet = meters ****into Google search box)

h = Hi + Vi t -4.9 t^2

0 = 1.22 + 5.3 t - 4.9 t^2
or
4.9 t^2 - 5.3 t -1.22 = 0

solve quadratic
t = [ 5.3 +/- sqrt (28.1+23.9) ]/9.8
use far answer
t = 1.28 seconds
1.28 * 2.37 = 3.03 meters
