physics question #5?
A light, inextensible cord passes over a light,
frictionless pulley with a radius of 13 cm. It
has a(n) 23 kg mass on the left and a(n)
9.5 kg mass on the right, both hanging freely.
Initially their center of masses are a vertical
distance 3.7 m apart.
The acceleration of gravity is 9.8 m/s2. At what rate are the two masses accelerating when they pass each other?
Answer in units of m/s
