Question

The angular velocity of a particle moving along a circle of radius 50cm is increased in 5 minutes from 100rpm to 400rpm find angular acceleration and linear acceleration

Answer 1

Answer:

n1 = 100 rpm = 100/60 = 1.67 rps. ... angular acceleration,α = ? ... α = ω2 − ω1t = 2 π (n2 − n1)tα = 2 π (6.67 −1.67)300 = 0.033 π rad s−2As linear acceleration, a = α r = 0.5 × 0.033 π = 0.0165 π ms−2.
