A light, inextensible cord passes over a light,
frictionless pulley with a radius of 11 cm. It
has a(n) 14 kg mass on the left and a(n)
4.3 kg mass on the right, both hanging freely.
Initially their center of masses are a vertical
distance 2.1 m apart.
The acceleration of gravity is 9.8 m/s2 .At what rate are the two masses accelerat-
ing when they pass each other?
Answer in units of m/s2
What is the tension in the cord when they
pass each other?
Answer in units of N
