Question

Ive followed a formula but still cant get it 

A stone is dropped at \( t = 0 \). A second stone, with 2 times the mass of the first, is dropped from the same point at \( t = 180 \, \text{ms} \). 

(a) How far below the release point is the center of mass of the two stones at \( t = 350 \, \text{ms} \)? (Neither stone has yet reached the ground.)

(b) How fast is the center of mass of the two-stone system moving at that time?

(a) Number: \( 0.155 \) Units: \( \text{m} \)

(b) Number: [Input required] Units: [Input required]
