Hi, Stuck on this one, I have a drawing but it does not make sense.
Is this 1D or 2D kinematics??
a hot air balloon is rising straight up with a speed of 3.0 m/s. A ballast bag is released from rest relative to the balloon when it is 9.5 m above the ground.
How much time elapses before the ballast bag hits the ground.
So I have Vo = 0 m/s as it's from rest relative to the balloon?? is that correct.
a = -9.8 m/ss
d = 9.5 m
Do I use d = Vot + 1/2 at^2. And if so how to do I get the 2 t's into 1. I tried to re arrange and it's not working out.
Please help me start this please, thanks. Tell me if I am on the right track.
