If it is frictionlss there is no force that has a torque.So it cannot roll.I think so

how is it going to roll if it is frictionless?

In both cases if you find the final speed of the mass(m) then you just use conservation of momentum

I don't know which one is correct so i will tell you two cases.(if some of them is correct) 1)I think that until the body leaves the spring we donnto have a conservation of momentum because the system Box-body(m) is not isolated as rhe force from spring ecxerts.When though the ball leaves the...

I got minus.Probably you forgot one minus.Chech your equations again.

In this case the tension is not only horizintal of vertcal but it has to componets.Try to analyze the tension.

I am sorry i misguide you

Sorry my mistake in the equation for body M there is no Mg there is Fcos35

Where is the minus in the 153.86?

It cannot because only backward from weight is above 1000.But it may mean that friction is 800 less or more.I donnot know but the mistake must be there

If i got it right then you have two equations with two unknowns. for the body m: mg-T=ma for the body M: T-Mg=Ma If you solve these two you will find an accelaration close to 0.78 i find 0.80 aproximatelly And then you can find the tension if you substitute the acc on one of the...

Could you please tell me the whole exercise?

It says drag nad friction add up to 800

Is something missing?Because you said initially it went back the body with the mass M and then you said about the force F

I don't said that the error was what the textbook said.i said that maybe you have misunderstood it.maybe it doesnot mean that T=800N
