AI Thread Summary
The discussion focuses on calculating the constant speed at which an elevator rises when powered by a 14kW motor and carrying a mass of 1100kg. The key equations referenced include the relationship between power, energy, and time, as well as kinetic energy. Participants emphasize that power is the rate at which work is done, leading to the formulation of a new equation that incorporates force and distance. The challenge lies in deriving the speed from the given power output and mass. Understanding these principles is essential for solving the problem accurately.

I'm only in high school physics so this may seem easy to you all XD

Homework Statement


The motor for an elevator can produce 14kW of power. The elevator has a mass of 1100kg, including its contents. At what constant speed will the elevator rise?

Homework Equations


P = E / T?
Ek = mv^2 / 2

The Attempt at a Solution



14000 = E / T
Ek = 1100v^2 / 2

If you use the fact that the power is the rate at which work is done by the motor (P = W/t), and that W = Fd, you can derive a whole new equation for power that consists of only quantities that are mentioned in the problem.

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...

Thread 'A cylinder connected to a hanged mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
