    Calculating Recoil Velocity from Alpha Decay

    so i can use the kinetic energy to find velocity then use p = mv to calculate the recoil? can't believe i didnt think of it that way. thanks.

    Calculating Recoil Velocity from Alpha Decay

    The nucleus of ^214 {Po} decays radioactively by emitting an alpha particle (mass 6.65 * 10^-27 kg) with kinetic energy 1.23 * 10^{-12} J, as measured in the laboratory reference frame. Assuming that the {Po} was initially at rest in this frame, find the magnitude of the recoil velocity of...

    Calculating Thermal Power Produced by Friction for a Sliding Rock

    F is not mg. F = umg or in other words the force of friction.
