Question: A hot air balloon is descending straight down at a constant speed of 5.00 m/s. When it is 30.0 m above the ground, a gun (at ground level) fires a pellet upward with an initial velocity of 30.0 m/s.
Part A: What is the velocity of the pellet and of the balloon when they have the same height above the ground? Hint: There are two answers, but only one of them is physically possible. You may assume freefall conditions for the pellet.
Having trouble with this physics question, can you please explain with the answer.
An infinitely long cylinder, radius a, carries a current I, distributed uniformly over its cross-sectional area. The axis of the cylinder coincides with the z-axis.
In damped harmonic oscillation I have the equilibrium height of my spring with weight, but not without. I know there is a method to finding this out but I don't know were to start. The equilibrium height with weight(.5kg) is .3192m. I have various gr..
