  • K1 = ½mV1²

    K2 = ½m(4V1)²

    K2/K1 = 16

  • Hey dude you should have say best answer WILL BE awarded.

  • 16.

    Kinetic energy = ½mv². If v gets 4 times bigger, v² get 4² = 16 times bigger.

  • From the ratio KE/ke = (V/v)^2 = (4v/v)^2 = 16 we see that KE = 16 ke; the energy increases by a factor of 16. ANS.

    HINT: When comparing the same variables at different values, using the ratios is the best way to solve the problem. EX: KE/ke = 1/2 mV^2/1/2 mv^2) = (V/v)^2 QED.
