Question

007 (part 1 of 2) 10.0 points A light, inextensible cord passes over a light, frictionless pulley with a radius of 7.2 cm It has a(n) 16 kg mass on the left and a(n) 6.7 kg mass on the right, both hanging freely. Initially their center of masses are a vertical distance 4.2 m apart. The acceleration of gravity is 9.8 m/s 7.2 cm 16 kg 4.2 m 6.7 kg At what rate are the two masses accelerat- ing when they pass each other? Answer in units of m/s- 008 (part 2 of 2) 10.0 points hat is the tension in the cord when they pass each other? Answer in units of N

Explanation / Answer

let

m1 = 16 kg

m2 = 6.7 kg

acceleration of objects,

a = g*(m1 - m2)/(m1 + m2)

= 9.8*(16 - 6.7)/(16 + 6.7)

= 4.01 m/s^2 <<<<<<<<<<-----------------Answer

tension in the string,

T = m1*g - m1*a

= 16*9.8 - 16*4.01

= 92.6 N <<<<<<<<<<-----------------Answer
