    Needed Power Output on an Incline

    I got it from the situation if the cyclist was going at 5 m/s on flat ground with no incline

    Needed Power Output on an Incline

    Homework Statement A bicyclist coasts down a 7 degree hill at a steady speed of 5 m/s. Assuming the total mass of 75 kg, what must be the cyclist's power output to climb the same hill at the same speedHomework Equations power = force * distance / time force of gravity = mass * gravityThe...

    How Is Tension Calculated in an Atwood Machine with Equal Masses?

    Ok. If you do the net force for each mass, both of them turn out to be T=mg. All you need to do is plug in the things you know since the equation is already solved for tension, the value you're trying to find. Tension = mg. It would just be g. Does that clear it up? I'm not sure if I explained...

    How Is Tension Calculated in an Atwood Machine with Equal Masses?

    Well first of all, you should acknowledge that the system has no acceleration. A pulley with equal masses will have no acceleration. Also, if the masses are equal, you no longer need the subscripts. Just label both of them "m." You can either do the drawing the free body diagrams or figure out...

    A 2.5 kg block and a 3.1 kg block slide down a 30 degree incline.

    I also have a question regarding this problem. It seems as though the people who have replied are addressing about how you would approach this question as a whole. I found the acceleration of this system but I want to know how to do part b of this question. I labeled the 2.5 kg block to be m1...
