30 4s T. Ti 4. Which of the following is true of the masnitudes of tensions Ti. T, and Ts in the ropes in the diagram shown above? (A) Ti must be greater than 30 N (B) The tension T: is greater than T (C) The y-component of T: and T is equal to 30 N (D) The sum of the magnitudes of T: and Ts is equal to Ti (E) The sum of the magnitudes of Ti and T: is equal to T. 5. Two blocks of mass m and Sm are connected by a light string which passes over a pulley of negligible mass and friction. What is the acceleration of the masses in terms of the acceleration due to gravity, g? (A)4g (B) 5g (C) 6g (D)4/5 g (E) 2/3 g

Explanation / Answer

Force on m, T-mg = ma

Force on 5m 5mg-T = 5ma

Solve for T and a,
a = 4mg = 6ma SO, 4g/6 = a
