Question

The pulley in (Figure 1) is suspended by a cord C . Suppose that m 1 = 1.4 kg and m 2 = 3.1 kg .

Part A

Determine the tension in the cord that supports the pulley C after the masses are released and before one hits the ground. Ignore the mass of the pulley and cords.

Express your answer to two significant figures and include the appropriate units.

Explanation / Answer

Or on m1: T - 1.4g = 1.4 a

on m2: 3.1g - T = 3.1 a

a = 3.7 m/s^2, T = 18.9 N

Tension in cord = 2 T = 37.8 N ......Ans
