    Two pendulums banging into each other problem.

    Homework Statement A system contains two metal balls hanging from strings of length !.0 m. Pendulum A has a mass of 2.0 kg and B has a period of 2.0s. They are released from the same height at the same time and collide right in the middle of their arcs. If pendulum A comes to a complete stop...

    What force is needed to produce a constant speed?

    The friction force is dependant upon the Normal force and coeffeiciant of friction. Is that correct? So would i calculate the coefficiant first with the normal force being = to 10(9.81) and the friction force equal to 75 N? Then as the mass increases the Fn will increase and i can multiply that...

    What force is needed to produce a constant speed?

    Homework Statement An empty wagon with mass 10 kg is pulled by a force of 75 N at a constant speed. Rain falls collecting in the wagon at a rate of 375mm^3/s. The density of water is 1g/mm^3. A) Make a table showing how much force must be exerted on the wagon to keep it moving at a constant...

    Satellite surrounded by four asteroids question

    So you would get an equation identical to (9.0x10^4)/(500^2)=(mass of asteroid C)/(1500^2). And you solve to get 8.1x10^5 kg? and then i would do the same with the Y axis asteroids? And for B, once I know their masses, is there where I would use a right triangle to find their distance and solve...

    Satellite surrounded by four asteroids question

    since the satellite is at equillibrium, that means there is no acceleration or unbalanced forced in the system. Am i right in that the only forces in action are the one that each asteroid has on the satellitle and the four oppositly directed forces the satellite has on the asteroids? I don't see...

    Satellite surrounded by four asteroids question

    Homework Statement A 100 kg satellite is surrounded by four asteroids. Asteroid A has a mass of 8.5x10^5 kg and is 800 km North of the satellite. Asteroid D has a mass of 9.0x10^4 kg and is 500 km West of the satellite. Asteroid B is 1200 km south of the satellite and asteroid C is 1500 km...
