Show that these three forms of writing equations for oscillatory motion are equivalent. (the constant a in the first equation does not have to be the same as the constant a in the third equation)
x(t) = aei? t + be-i? t
x(t) = csin(? t) + dcos(? t)
x(t) = asin(? t + ? )

Amachinist turns the power on to a grinding wheel, at rest, at time t = 0 s. the wheel accelerates uniformly for 10 s and reaches the operating angular velocity of 96 rad/s. the wheel is run at that angular velocity for 40 s and then power is shut off. the wheel slows down uniformly at 1.5 rad/s2 until the wheel stops. in this situation, the time interval of deceleration is closest to:
