A remote controlled car's wheel accelerates at 44.5 rad/s2. If the wheel begins with an angular speed of 11.5 rad/s,
a) What is the wheel's angular speed after exactly 4 full turns?
b) How long does the wheel take to make the 4 turns?
would i have to use angular kinematic equations? But i am not sure what 4 full turns wouls translate to
4 full turns are 8Pi
so 8Pi = 1/2*44.5*t^2 + 11.5t
0 = 22.25t^2 + 11.5 t - 25.13
Solve for t
t = 0.835293 s is the time to do 4 turns.
By then the wheel speed will be
w = 11.5 + 44.5*0.835293 = 48.67 rad/s
