1. The problem statement, all variables and given/known data Two objects A and B weighing 50 N and 80 N respectively were connected by a light string over a fixed pulley. A was put on a reasonably long and horizontal table surface. The coefficient of sliding friction between A and the table surface is μ = 0.3 while the friction between the string and the pulley is neglected. Find the velocity of B after falling downwards for 2m. (Take g = 10 ms^-2) Wa = 50 N Wb = 80 N μ = 0.3 3. The attempt at a solution The question given that the object B falls when at start, thus when object B falls the tension change as the angle change, cant even start the 1st equation.
