blocks, M2 = M1 but of different sizes, having the
same speed, move from a frictionless surface onto a surface having
friction coefficient μk.

Which stops in the shorter time?

  1. M1
  2. M2
  3. Both stop in the same time
  4. Cannot be determined



(3) Both blocks will experience the same acceleration. If they
have the same initial velocity, they will stop in the same time.
