A costant force F=20N acts on a block of mass 2kg which is connected to two blocks of masses m1=1 kg and m2=2 kg.Calculate the accelerations produced in all the three blocks.Assume that pulleys are frictionless and weightless.
Let, F be the force applied to the system. The total mass of the system is m = 2kg + 1kg + 2kg = 5 kg
So, acceleration of the system, a = F/m = (20/5) m/s 2
thus,
a = 4 m/s 2
