I am confuse with the following Kinematics problem
PROBLEM
A helicopter accelerates uniformly upward at 1m/s^2 to a height of 300 m. Determine the time required for this motion.
SOLUTION
s = 300 m
v0 = 0
a = 1 m/s^2
v = v2
s = (v0) (t) + (1/2) (a) (t^2)
300 m = 0 + (1/2) (1m/s^2) (t^2)
t = 24.5 s
QUESTION
As the Helicopter move upward, there should exist any Gravitational Acceleration downward.
But as you can see on the Solution the only available acceleration is the helicopter acceleration.
Can anyone here tell me what’s wrong with the Gravitational Acceleration?
Please advance
Tom
