A 7.7-N force pulls horizontally on a 1.6-kg block that slides on a smooth horizontal surface. This block is connected by a horizontal string to a second block of mass m2 = 0.83 kg on the same surface.

A) What is the acceleration of the blocks?

B) What is the tension in the string?

C) If the mass of block 1 is increased, does the tension in the string increase, decrease or stay the same?
