A car moves with a constant tangential acc. A(t)=2/3 m/s2 along a horizontal surface circumscribing a circle of radius r = 40 m. The coefficient of sliding friction between the wheels of car and the surface is us = 0.20 . What distance will the car ride without sliding if at the initial moment of time its velocity is equal to zero? Take g = 10 m/s2
nobody tried !!!!!!!!!!
but it's ok, problem has been solved............
Sorry for late reply.Is the answer 3.749 m?If it is not, then can you please post the solution?
Sorry........................not correct.........!
answer is 40(2)1/2
Have one more try .................
because it can be done by 2 methods,both of which give same answer.......but only one is correct.........
GOOD LUCK!
Yes .Lokesh, the answer I am getting is 40(2)1/2.I just want to discuss the method with you.Friction will act against the resultant force.From this we will get the safe limit for speed(v). v=a(T) t.t can be calculated.Distance moved by the car=1/2 a(T)t^2.Is this how you have done?
