Posted by Need help on Saturday, June 16, 2012 at 11:16pm.

1.A 4.5kg object is at rest on a table with state friction of 0.56 and kinetic friction of 0.46. A force is applied such that the object just beings to move. If that same force is maintained, at what rate will the object accelerate?
The answer is 0.98m/^2
2.A 2.0kg block is at rest on a table. At what rate will it accelerate when a force of 6.5N is exerted on the block?
The answer is 0m/^2
Can you please explain how to get those two answers? THANK YOU!
