    Acceleration of Protons and Electrons at a certain distance provided.

    Sorry, I meant 3.16 x 10e20. Still isn't correct though.

    Acceleration of Protons and Electrons at a certain distance provided.

    Homework Statement If a proton and an electron are released when they are 8.00×10e-10 m apart (typical atomic distances), find the initial acceleration of each of them. Homework Equations F=ma F=kq1q2/re2 F=kee2/r2 The Attempt at a Solution Since r=8x10e-10, I solved for the...

    What is the Work Done on a Carton on an Inclined Ramp?

    Well, i figured out the work done on the carton by the rope because the angle of the rope is NOT 30 degrees, it is parallel, thus 0degrees. Still can't figure out the gravity one though..

    What is the Work Done on a Carton on an Inclined Ramp?

    Homework Statement A 128 N carton is pulled up a frictionless baggage ramp inclined at 30.0 degrees above the horizontal by a rope exerting a 72.0 N pull parallel to the ramp's surface. If the carton travels 5.20 m along the surface of the ramp, calculate the work done on it by the rope...

    Kinetic Friction to find velocity

    Thank you, our physics book and teacher never explained that to us. Just to get this right, you said that (Force) F = mu x m (mass) x g (gravity)?

    Kinetic Friction to find velocity

    Right, i got the answer... but what is the formula a= (mu x g). I have never seen this formula before. Is this derived from something else??
