If a cycle wheel of radius 0.4 m completes one revolution in one secon

1.	If a cycle wheel of radius 0.4 m completes one revolution in one second, then acceleration of the cycle is(A) 0.4 π m/s2 (B) 0.8 π m/s2 (C) 0.4π2m/s2 (D) 1.6π2 m/s2
Answer» Answer is (D) 1.6π² m/s² Using, ω = 2πn = 2π x 1 = 2π rad/s a = rω² = 0.4 x (2π)² = 0.4 x 4 π² a = 1.6 π² m/s²

If a cycle wheel of radius 0.4 m completes one revolution in one second, then acceleration of the cycle is(A) 0.4 π m/s2 (B) 0.8 π m/s2 (C) 0.4π2m/s2 (D) 1.6π2 m/s2

Answer»

Answer is (D) 1.6π² m/s²

Using,

ω = 2πn = 2π x 1 = 2π rad/s

a = rω² = 0.4 x (2π)² = 0.4 x 4 π²

a = 1.6 π² m/s²
