A sled is accelerating down a hill at a rate of 1 m/s2
. If the mass of the sled is suddenly cut in half and the net force on the sled is doubled, what is the acceleration of the sled?

  • physics -

    net force=mass*acceleration

    so doubling net force doubles acceleration, and cutting mass in half, doubles it again.
    Answer: 4 time original acceleration.
