Question
A wheel is at rest. Its angular velocity increases uniformly and becomes 80 radian per second after 5 second. The total angular displacement is :
Options
A.800 rad
B.400 rad
C.200 rad
D.100 rad
Solution
ω = 80 rad/sec, t = 5 sec, ω0 = 0
θ = ?
If α constant, then
θ =
t = 
5 = 200 rad Ans.
θ = ?
If α constant, then
θ =
t = 5 = 200 rad Ans.Create a free account to view solution
