A high-jumper clears the bar and has a downward velocity of -6.00 m/s just before landing on an air mattress. The mass of the high-jumper is 53.7 kg. What is the magnitude and direction of the impulse that the air mattress exerts on her? Assume that upward is the positive direction.

  • Physics(Please help) - ,

    impulse=change of momentum
    impulse=mass(final velocity-intial velocity)
    = 53.7(6) kg m/s
