Question

Three blocks with masses of 1kg, 2kg and 3kg are connected to each other by light strings with equal distances from each other. The system is pulled by a horizontal force of 18N at the 3kg block, (last in the system). If the coefficient of friction between surfaces in contact is 0.12, find the acceleration of the system and the tension in each of the string.

Answer 1

Answer:

Equation of force is given by

F=(2+3+5)a

10=10a

a=1m/s

2

Now T

1

=F−2a

T

1

=10−2×1

T

=8N
