Question

А A cycle wheel of radius. 0.4 m completes one revolution in one second then the accelaration of a point on the cycle wheel will be (A) 0. 8 m/s² (B) 0.4 m/s² (C) 1.67 π²m/s² (D) 0.4 π²m/s²

please answer​

Answer 1

Using

ω =2 πn = 2  π × 1

 =2 π  rad/ s

a =r ω²  = 0.4  ×(2 π)²

a =1.6 π² m/s²

  = 0.4×4 π²

option D is correct
