You are piloting a helicopter which is rising vertically at a uniform velocity of 14.70 m/s. when you reach 196.00 m, you see barney. you project a banana with a horizontal velocity of 8.50 m/s from the rising helicopter, with the mean intent to get barney. when does the banana reach barney's head, if he is 1.70m tall?

7.97 seconds

Explanation:

Distance to travel is 196-1.7=194.3m

Considering that this is vertical motion then using the equation of motion

where s is the distance to travel, u is initial velocity, t is timw and g is acceleration due to gravity

Substituting s for 194.3, u for 14.7 m/s and a for 9.8

This is a quadratic equation which is in the form of then to solve x we use quadratic formula

t=(14.7+\sqrt (14.7^{2}-(4*4.9*-194.3))/(2*4.9)

t=7.97 seconds
