A 4.0 kg block, lying on a smooth table, is connected to another 5.0 kg block by means of a weightless cord passing over, without slipping, a cylindrical pulley of 2.0 kg mass and 10.0 cm radius placed at the edge of the table. The system is released from rest at t = 0. Denote a, the acceleration of the system. Consider g=9.8 m/s2.
(a) The ratio g/a for the 5.0 kg block is ________
(b) The net torque on the pulley is ________
m1 = 20 kg, determine the mass of m2 which will cause the system to stay in equilibrium. The pulley does nothing other than change the direction of the force from the hanging mass.
Two blocks with m₁ = 15.1kg and m2 20.0kg shown below, are connected by a string of negligible mass passing over a pulley of radius 0.214m
and a moment of inertia I. The block on the frictionless incline is moving upward with a constant acceleration of 2.01m/s² on an angle of 38.8° to the
horizontal. Determine the tension T₁.
