Question

If a mass is tripled, speed is halved and radius is doubled, what happens to the centripetal acceleration?

Answer 1

I believe acceleration would be \[\frac{ 1 }{ 8 }\]
since ma=\[\frac{ mv ^{2} }{ r }\]
Both sides should be equal

Answer 2

so the mass doesn't matter?? O.O

Answer 3

oh yeah, because they will cancel out >.<

Answer 4

thanks!
