Dr. Evil Problem

  1. Sep 18, 2009 #1
    Can somebody help me please to solve this problem?

    helicopter carrying Dr. Evil takes off with a constant upward acceleration of Secret agent Austin Powers jumps on just as the helicopter lifts off the ground. After the two men struggle for 10.0 s, Powers shuts off the engine and steps out of the helicopter. Assume that the helicopter is in free fall after its engine is shut off, and ignore the effects of air resistance. ( a) What is the maximum height above ground reached by the helicopter? ( b) Powers deploys a jet pack strapped on his back 7.0 s after leaving the helicopter, and then he has a constant downward accel-eration with magnitude How far is Powers above the ground when the helicopter crashes into the ground?

    Hi kero! Welcome to PF! :smile:
    we can't help you …

    if the acceleration is Secret! :biggrin:

    Use the usual constant acceleration equations …

    show us how far you get, and where you're stuck, and then we'll know how to help! :smile:
