Question
A photographer in a helicopter ascending vertically at a constant rate of 1.3 m/s accidentally drops a camera out the window when the helicopter is 40.0 m above the ground. How long will it take the camera to reach the ground?
Which equation should I use?
a) Y=Yo + Vo(t) + (1/2)(-g)(t^2)
b) V=Vo + (-g)(t)
c) (V^2)=(Vo^2) + 2(-g)(Y-Yo)
d) Y-Yo=(1/2)(V-Vo)(t)
