Yeah but mass is a scalar.. and your saying the mass would be distributed in the x and y directions based on the angle that it makes with the axis... I'm trying to put it in perspective to understand why it's true

Thank you. So can you explain how it is the masses are dependent on the angle exactly? Here's what I think. The force of gravity itself is along the line that connects the two particles. This force depends on the masses of the particles as well as the inverse square of total distance between...

So , essentially what I was trying to do was to take two asteroids of the same mass , one 3.00km horizontally from the ship and one 1.50km vertically from the ship and try to equate that to one asteroid of that mass that is 3.00km horizontally and 1.50km vertically from it .. which now makes...

1. Homework Statement The millennium eagle passes between a pair of asteroids, as shown. If the mass of the spaceship is 2.50 x 10⁷kg and the mass of each asteroid is 3.50 x 10¹¹kg, find the net gravitational force exerted on the millennium eagle at point (A) and point (B). Treat the asteroids...

aha so you solve for the time knowing speed and distance. Would it then be correct to insert this time into the equation P = (Ui-Uf)/t ?

How can we relate potential energy to the power? Maybe P = (Ui - Uf)/t how can we solve this

W = Uf - Ui Uf of the cab is 0 Uf of the counterweight is 2600*9.81*300 = 7651800J Ui of the cab is 2000*9.81*300 = 5886000J Uf - Ui 7651800J - 5886000J = 1765800J So the work is going to be 1765800J

Also W = Ui - Uf

W = Kf - Ki W = .5MVf^2 - .5MVi^ 2

Homework Statement The mass of the cab is 2000kg and the mass of the counterweight in an elevator is 2600kg. Assume the mass of the cab remains constant. The cab must descend a distance of 300m from the top floor to the bottom floor, and must do so at a constant speed of 10m/s. A)What must...
