Question

11. A horizontal cord is attached to a 6.0-kg body in a horizontal table. The cord passes over a pulley at the end of the table, and to this end is hung a body of mass 8 kg. Find the distance the two bodies will travel after 2s if they start from rest. What is the tension in the cord? 

Answer 1

$$(6+8)a=8(9.8)\\a=5.6\frac{m}{s^2}\\s=0.5(5.6)(2)^2=11.2\ m$$
