Thank You Shooting Star and Doc Al. I found my mistake, I was using 1/2MR^2 for the Inertia of the mouse, instead of MR^2. Thank you

by "Final KE of same" you mean KE of the disk and the mouse would the KE of the mouse at the center of the disk be 0, so only the KE of disk would be involved in the final right

Homework Statement A turntable of radius 25 cm and rotational inertia 0.0154 kg m^2 is spinning freely at 22.0 rpm about its central axis, with a 19.5-g mouse on its outer edge. The mouse walks from the edge to the center. Find (a) the new rotation speed and (b) the work done by the mouse...

thanks, I solved the problem

At liftoff, a space shuttle with 2.0 x 10^6 kg total mass undergoes an upward acceleration of 0.60g. Find the total thrust force developed by its engines?What force does the seat exert on a 60-kg astronaut during liftoff? Thank you for helping with the problem
