Free Fall simple question, Answer check ASAP please! Homework Statement A flying squirrel falls from the top of a tree, without initial velocity. It travels the last 2 meters of its fall in 0.2s. What was the height of the tree?Homework Equations d=\upsilon_{i}t + \frac{1}{2}at^{2}...

Thank you for responding LeonhardEu! Ok, so since C is initially neutral, I don't need to take it into account for the first problem? So according to that, I would find the \vec{F}_{elec} of spheres A and B, ie I used Coulombs law? But after that, I'm not sure how I would find the point that...

Hmm, I don't understand why that wouldn't make sense. It clearly states in the questions that the small object causes the two balloons to float. Why isn't it considered in this problem? I thought it was only the masses of the balloons that are ignored here. No, I didn't. Would I then need to...

Homework Statement As indicated in the diagram, consider a rail inclined at an angle θ relative to the horizontal axis. A sphere (A) with a charge +q is fixed at the bottom of the rail. A second sphere (B) with a charge +2q and a mass (m) is free to move along the rail. The sphere (C)...

Hello mfb, Thank you for taking the time to respond! No, the diagram is not upside down. That's exactly as it appears in the problem. From what I understand it's the mass that causes the two balloons to float up. It's lifted upwards from the bottom towards the two balloons thus causing...

Homework Statement An object with a small mass (m) causes two balloons to float (neither ascending nor descending) in the air at a fixed distance from each other, as shown in the diagram. The balloons, with a volume (V) each carry a positive charge, Q. The balloons are said to be point...
