ballon modelling
livelovelaugh asked:

1. A small sandbag is dropped from rest from a hovering hot-air ballon. After 2 s, what is the sandbags displacement below the balloon?
Can someone tell me what to do step by step.

2. A model rocket is launched straight upward witha n initial speed of 50.0 m/s. It accelerates with a constant upward acceleration of 2.00 m/s ^2 until its engines stop at an altitude of 150 m.
–What is the maxiumum height reached by the rocket?
—When does the rocket reach maxium height?
—How long is the rocket in the air?

Please tell me what to do step by step, I want to learn how to solve it.

    1) displacement = .5gt^2 = .5(9.8)(2)^2 = 19.6 meters.
