Two objects are in contact on a frictionless surface. A horizontal force is applied to one object as shown in the figure below. Use m1 = 1.2 g, m2 = 254 g and F = 0.7 N to find the force between the two objects.

1 answer

Let f be the force between them, pushing on each other.

F - f = m1*a
f = m2*a

Ypu have two unknowns (a and f) and two equations.

Add the equations to get rid of f.

F = (m1 +m2)a

Now solve for f
