Calculating Ball Velocity Dropped From Moving Helicopter

AI Thread Summary
When a ball is dropped from a helicopter moving vertically at 5.0 m/s, its initial velocity is 5.0 m/s relative to the helicopter. However, the ball's velocity relative to the ground depends on the helicopter's vertical direction. If the helicopter is moving upward, the ball's initial velocity is 5.0 m/s upward. If the helicopter is descending, the ball's initial velocity would be 5.0 m/s downward. The discussion highlights the importance of clarifying the helicopter's vertical motion to determine the ball's initial velocity accurately.

This might be a stupid question, but if a helicopter is moving at 5.0 m/s vertically, and one drops a ball off the helicopter, what is the original velocity of the ball?

5m/s... relative to the ground and it will be in rest relative to the helicopter. Ofcourse only a splitsecond later this will not be true and the ball will accellerate under the influence of gravity.

Only if the helicopter was moving upward. The original post said vertically, so you don't know if it's moving upward or downwards.

if your trying to rack up posts, go ahead, but comments like that are not needed. :smile:

K, you are right, I was trying to be too accurate...over such an obvious thing. :blush:
 
The rope is tied into the person (the load of 200 pounds) and the rope goes up from the person to a fixed pulley and back down to his hands. He hauls the rope to suspend himself in the air. What is the mechanical advantage of the system? The person will indeed only have to lift half of his body weight (roughly 100 pounds) because he now lessened the load by that same amount. This APPEARS to be a 2:1 because he can hold himself with half the force, but my question is: is that mechanical...
Some physics textbook writer told me that Newton's first law applies only on bodies that feel no interactions at all. He said that if a body is on rest or moves in constant velocity, there is no external force acting on it. But I have heard another form of the law that says the net force acting on a body must be zero. This means there is interactions involved after all. So which one is correct?
Thread 'Beam on an inclined plane'
Hello! I have a question regarding a beam on an inclined plane. I was considering a beam resting on two supports attached to an inclined plane. I was almost sure that the lower support must be more loaded. My imagination about this problem is shown in the picture below. Here is how I wrote the condition of equilibrium forces: $$ \begin{cases} F_{g\parallel}=F_{t1}+F_{t2}, \\ F_{g\perp}=F_{r1}+F_{r2} \end{cases}. $$ On the other hand...
