Question

two boxes sit on a frictionless surface and are in contact with one another. the first box has a mass of 7 kg and the second box has a mass of 8 kg. A 25 N force is applied to the 7 kg box. Find the acceleration of the boxes. find the force between the boxes

Answer 1

the acceleration of the boxes depends on the mass and weight.

we have a mass of 7 and 8 kilograms

if it took 25 N force to move box A, then you would take 25 and multiply by 8 then divide by 2.

It will leave you with 100 N.

finally take the sq rt of 100 to get 10
