A7.7-N force pulls horizontally on a 1.6-kg block that
Chapter 6, Problem 49(choose chapter or problem)
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 \(m_{2}=0.83 \mathrm{~kg}\) 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?

ANSWER:Step 1 of 4
a)
free body diagram shown below
Given values
Force acting on block 1, F = 7.7 N
Mass of block 1 \(m_{1}=1.6 \mathrm{~kg}\)
Mass of block 2, \(m_{2}=0.83 \mathrm{~kg}\)
Let the tension in the string be T
