Question

Three blocks of masses 1.0, 2.0, and 4.0 kilograms are connected by mass less strings, one of which passes over a friction less pulley of negligible mass, as shown. Calculate each of the following. 

a. The acceleration of the 4-kilogram block 

b. The tension in the string supporting the 4-kilogram block 

c. The tension in the string connected to the l-kilogram block 

Answer 1

c. Similarly for the 1 kg block: T₁ – mg = ma gives T₁ = 11.2N
