(adsbygoogle = window.adsbygoogle || []).push({}); 1. Three blocks are in contact with each other on a frictionless horizontal surface.The masses of the blocks are m1 = 1 kg , m2 = 2 kg, m3 = 3 kg. A horizontal force F = 24 N is applied on m1.

a. Find the net force on each block.

b. Find magnitude of the contact forces between the blocks.

2. Relevant equations

F= ma

3. The attempt at a solution

I found the net acceleration, that equals to Fnet/(m1+m2+m3)

and then for a) I just multiplied each mass by net acceleration to get the force. Like for mass 3, I multiplied net acceleration by mass 3

and then for b)

between the m1 and m2

Net force on m1 is force applied - force exerted on it by m2

and the force exerted by the forward masses equal to summ of m2+m1 divided by m1+m2+m3, and times total force<24 N>

..... <I get lost after this>

I am confused for both parts. Wondering if I am on right track?
