why we cannot resolve force in upward direction like this as i do in green colour box.
how to solve it?
What is the mechanical advantage of single fixed pulley
sir,my ans is 16.5...from the que, 10a=3t*2-32.......the value of 3t* is 45 so by this acceleration comes 1.3ms*2...and by implying v=u+at=the velocity comes 16.5.....sir please tell me where i am wrong?
Why did the acceleration at one place on string became zero?
