thanks =) i think i get it

the question asks what would you experience... i thought somehow the force pushes you off the disc but if the force is decreasing, then nothing happens?

wait I am confused... so if one is to walk towards the center and the radial acceleration is decreasing, wouldn't the force decrease too? so what would happen? I am sorry I am kinda confused

so one would not experience any force? i was told that you would experience a force pushing you off the disc

does a=angular velocity squaredX radius matter? in tht case would the centripetal acceleration decrease?

You stand on the edge of a large rotating disc. It rotates at a constant speed. You walk towards the centre of the disc. What do you experience? radius is decreasing, therefore inertia and linear velocity are decreasing. but angular acceleration will increase. i don't know if I'm right

yea i just checked my email =/ too much work!

lol ace123 yeaa i just saw ur post

oh ok... am i right about the second question? after the collision since they are together where would the CM be and the velocity ?

thank you...i think i get it... i had another question with a similar problem Two identical balls, each with velocity v, strike each other at right angles to each other. They stick together. Ignoring friction, (a) describe the motion of the combined ball after the collision and (b) describe the...

since its the other billiard ball that is traveling with a velocity v, now the center of mass is traveling with velocity v

velocity v

no as the first ball gets closer, the center of mass chnages to remain in the middle of both...?

would it be half way between them?

in the middle of the ball ?
