# Thread: Friction and two masses

1. ## Friction and two masses

Two blocks are in contact on a frictionless table. A horizontal force is applied to the larger block, as shown in Fig. 5-51. (a) If m1 = 2.1 kg, m2 = 1.7 kg, and F = 2.7 N, find the magnitude of the force between the two blocks. (b) Assume instead that a force of the same magnitude F is applied to the smaller block but in the opposite direction, and calculate the magnitude of the force between the blocks. (Why is the value calculated in (b) not the same as that calculated in (a)?)

Problem 53.

Although there are a few guys floating around here that can do this stuff, you will have better luck here:

This is MHF's sister site. Please stop by if you have any physics questions or want to give physics help!

I tell you this for the future. You'll probably get someone to help today though.

Good luck! And welcome to MHF.
