One more newton laws

  1. Aug 30, 2008 #1
    Object A placed on a floor frictionless and object B placed on object A.
    The drag coefficient between A & B is 0.3
    The length of A is 1m and the length of B is 30 cm .
    a force of 100N workin on object B.
    What is the time take to the edge of object B placed on the edge of object A ?

    all i received its that acceleration of B a = 7.06

    How did you calculated the acceleration?

    Remember that in case of a linear motion: s =1/2*a*t^2.

    Did you calculate this or was it given to you? This is the acceleration of which block?
    Which block is this? Please show your work.
