1) does a perfectly rolling + translating body(consider a sphere) keep on rolling and translating forever on a rigid surface, given that no force is acting on it? 2) when a retarding force acts on the centre of rolling + translating body, does the angular velocity(w) of the body also change given that v= r.w?

Hi I am 17 and just about to enter college. I am good in studies and all that. Now here s the thing. Few months ago I heard someone talking about going after their dreams and I kinda gave it a deep thought on what I really wanted to do. I realised that I have always wanted to become an EDM music producer but never gave it a serious thought. From that moment onwards all I really was thinking about EDM and music while still continuing my studies. I talked about this to my family members but they heavily criticized the idea. What should I do? Should I start working secretly on it in my college days? Thank you.

Two particles of masses m1 and m2 in projectile motion have velocities v1 and v2 respectively at t=0. They collide at t=t1. Their velocities become v1 and v2 at t= 2t1 while still moving in the air. The value of |(m1v1 + m2v2 )-(m1v1+m2v2)| is? The answer is 2(m1 + m2)gt1. How?

when one of the capacitor plates is already given a charge and the second place is brought near it and connected to an EMF source then will the charge on both plates be equal.
