Questions
A wheel is rotating at 900 rpm about its axis. When power is cut-off, it comes to rest in 1 min. The angular retardation (in rad s-2) is
detailed solution
Correct option is A
Angular velocity, ω0=900×2π60rads-1=30πrads-1Now, 0=ω0-αt∴ Angular retardation, α=ω0t=30π60rads-2=π2rads-2Talk to our academic expert!
