A 0.45-kg mass oscillates according to the equation
where the position x(t) is measured in meters.
Part (a) What is the period, in seconds, of this mass?
Part (b) At what point during the cycle is the mass moving at its maximum speed?
Part (c) What is the maximum acceleration of the mass, in meters per square second?
Part (d) At what point in the cycle will it reach it's maximum acceleration?
O It changes from cycle to cycle.
There is not enough information to answer.
O At equilibrium points of the cycle.
O At the maximum displacement of the cycle.
O At 1/4 and 3/4 points in its cycle.
Part (b) At what point during the cycle is the mass moving at its maximum speed?
O It will change from cycle to cycle.
O There is not enough information to answer.
O When displacement approaches the maximum amplitude.
O At the equilibrium points in the middle of the cycle.
© At the equilibrium points and at the maximum amplitudes.
x(t)=0.38 cos(12.5t),
