two bodies 11 and 11.5 kg are connected by a long inextensible string passing over a frictionless pulley.calculate velocity and hieght ascended/descended by each body at the end of 4 seconds
This being Atwood machine a=(m-m')g/(m+m')=5/22.5
You can find v from v=u+at and y from y=ut+(1/2)at2 where u=0 and t=4.
