Can a tug of war be ever won on a frictionless surface?

Three blocks masses 4kg 6kg and 8kg are connected by a string they are placed on a frictionless surface if the system is pulled by a force of F=36 N then acceleration of the body is a = and tension acting on the sting is T= Which of the following pair is correct

A bullet hits and gets embedded in a solid block resting on a frictionless surface. In this process which is correct ?

A 40N force pulls a system of three masses on a horizontal frictionless surface the value of tension T_(1) is

A body is moving at constant speed over a frictionless surface. What is the work done by the weight?

A block of mass m slides along a frictionless surface as shown in the figure. If it is releases from rest from A what is its speed at B?
