Homework Statement
A wheel is spinning at 43rpm with its spin axis vertical. After 15s , it's spinning at 62rpm with its axis horizontal. Find (a) the magnitude of its average angular acceleration.
ans:______rad/s/s
Homework Equations
[tex]\alpha[/tex] = [tex]\varpi[/tex] /t
attempt :
change in omega is 2pi/60 (62-43)
t = 15
so divide them to get rad/s/s
=
1.3 * 10^-1
