The system shown consists of thin circular disk A (IG=0.5*m*r2) with a mass of 10kg and a radius of 10cm and weight B with a mass of 20kg. If the system starts at rest with the spring uncompressed find the speed of weight B once it falls 0.5m. The spring constant k is 100N/m. Use g=10m/s² downwards to simplify your calculations. Assume the pulley with the hashed center is free to rotate and the rope is light. Assume rolling without slipping. Your work must include a diagram and the answer must be proven. A k WW A

Question

student submitted image, transcription available below

The system shown consists of thin circular disk

A (l_{G} = 0. 5^{?} m^{?} r^{2})

with a mass of

10 kg

and a radius of

10 cm

and weight

B

with a mass of

20 kg

. If the system starts at rest with the spring uncompressed find the speed of weight

B

once it falls

0.5 m

. The spring constant

k

is

100 N / m

. Use

g = 10 m / s^{2}

downwards to simplify your calculations. Assume the pulley with the hashed center is free to rotate and the rope is light. Assume rolling without slipping: Your work must include a diagram and the answer must be proven.
