5.91(approx) seconds just divide velocity by acceleration
Answer:
Explanation:
Given
Object is thrown with a velocity of
Acceleration due to gravity is -g (i.e. acting downward)
Vertical distance traveled by object is given by
where v=final velocity
u=initial velocity
a=acceleration
s=displacement
at maximum height final velocity is zero
time taken to reach maximum height
using
v=u+at
0=9-gt
