  1. You push crate "A" of mass M across a frictionless floor with constant force F. At the same time a friend pushes crate "B" of mass 2M across the floor with 2xF. When you have finished:
    • A. KEB = 4KEA
    • B. KEB = 2KEA
    • C. KEB = 1.4KEA
    • D. KEB = KEA
    • E. KEB = 1/2 KEA

  2. You throw ball "A" upward with velocity vA. A friend throws identical ball "B" upward with vB = 2 vA.
    • A. hB = 4hA
    • B. hB = 2hA
    • C. hB = 1.4hA
    • D. hB = hA
    • E. hB = 1/2 hA
