@wasiqss How is it 50 pi radians per second? If you contradict an answer you should provide a reason.

    the speed was 25 m/s,so it means 25 rev in one second, hence 1 rev = 2pie so multiply 2 pie with 25

    25 m per second does not mean 25 rev in 1 sec since 1 rev is pi m not 1 meter

    it would help if we know size of wheel

    a truck is moving at a rate of 90km/hr, and the diameter of its wheel is 1 meter. find the angular speed of the wheels in radians per second.

    diameter was one meter

    Yep so 1 revolution is C = Pi times diameter or pi meters

    90000 ------- = cycle per hours 2 pi .5 90000 ------- 1/3600 = cycle per second 2 pi .5 90000 ------- *2pi*1/3600 =(90000/.5)*1/3600= radian per second

    i rev= 2pie, hence 25 rev means 50 pie
