how much tension must a rope withstand if it is used to accelerate a 1200-kg car vertically upward at .80 m/s^2?

  • 12th grade Physics -

    Force required to accelerate the car vertically = m * (v^2)

    = 1200 * (0.8^2)

    = 1200 * 0.64

    This force will be equal to the tension on the rope.

    these are the answer choices though

    Problem 10
    13000 N
    12000 N
    11000 N
    10000 N

    tension=mg+ma=m(9.8+.8)= to two decimal places.
