Two in-phase sources of waves are separated by a distance of 4.00 m. These sources produce identical waves that have a wavelength of 5.50 m. On the line between them, there are two places at which the same type of interference occurs. (a) Is is constructive or destructive interference and (b) where are the places located?

The 'net' force acting on the box is (9 - 3) = 6 newtons
in the direction that Carlos is pushing.

Force = (mass) x (acceleration)

6 = (3) x (acceleration)

Divide each side by 3 :

2 m/s² = acceleration
