Question

The body of mass10kg revolves in a circle of diameter 0.4m making 100 rev/min .calculate its linear velocity,centripetal acceleration&centripetal force?

Answer 1

Explanation:

Angular velocity = ω = [rev/sec] x 2 π = 2π x frequency = 100 x 2π/60 = 4.18 rad/sec

Linear velocity= ω x radius = 4.18 x 0.2 = 8.36 m/s

Centripetal acceleration= v²/r = 8.73 m/s²

Force = ma = 10 x 8.73 = 87.3 N
