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?
[tex]\Sigma_F_=ma[/tex]
f=ma
mBg*0.3=ma
Which block is this? Please show your work.
