Two boxes of fruit on a frictionless horizontal surface are connected by a light string as in the figures below, where m1 = 15 kg and m2 = 17 kg. A force of 58 N is applied to the 17 kg box. The acceleration of the boxes is 1.8.
Find the tension in the string.
you take the mass of the object that the force is acted upon, in your case, 15kg and multiply that by you acceleration
T = (15)kg x 1.8 m/s^2 = 27N
