Hi, This is my first question and I am very stuck on it. I really need your help on this as this is due tomorrow and I just found out this forum today.
Q) A model rocket is launched straight upward with an intial speed of 50.0 m/s. It accelerates with a constant upward acceleration of...
A model rocket has a constant upward acceleration of 40.0 m/s^2 while its engine is running. The rocket is fired vertically, and the engine runs for 2.50 s before it uses up the fuel. After the engine stops, the rocket is in free fall. The motion of the rocket is purely up and down. i have two...
A model rocket is fired vertically upward from rest. Its acceleration for the first three seconds is a(t)=60t, at which time the fuel is exhausted and it becomes a freely “falling” body. Fourteen seconds after the fuel is exhausted, the rocket’s parachute opens, and the (downward) velocity slows...
model rocket - free fall acceleration again :(
The problem states:
A model rocket fired vertically from the ground ascends with a constant vertical acceleration of 4.0 m/s^2 for 6.00 seconds. Its fuel is then exhausted, so it continues upward as a free-fall particle and then falls back down...
