Question

2). A wheel is found to have a rotational rate of 24rev/s. it isgivenan acceleration of unknown for 4sec and during this time itgoes throught 33 revolutions. Find acc or deac in rad/s^2.

for this problem I did this Inital speed w=24/s 24*2pie rad/60 = 2.51 rad/s
Acceleration unkown 33/4s 33*2pie rad/4s 51.83 rad/s

Please let me no if I missed a step or just did itwrong.. 2). A wheel is found to have a rotational rate of 24rev/s. it isgivenan acceleration of unknown for 4sec and during this time itgoes throught 33 revolutions. Find acc or deac in rad/s^2.

Explanation / Answer

WE know that     = ot + (1/2)t2     33(2)rad = (24(2) rad/s)(4s)+(1/2)(4)2 Solve for .
