Questions
The angular velocity of a particle moving in a circle of radius 50 cm is increased in 5 min from 100 revolutions per minute to 400 revolutions per minute. Find the tangential acceleration of the particle.
detailed solution
Correct option is D
α=ω2-ω1/t=(400-100)/5=60 rev min-2 =60×2π(60)2=2π60rads-2 at=αr=2π60×50100=π60 ms-2Talk to our academic expert!
