Physics

An object with mass 0.190 kg is acted on by an elastic restoringforce with force constant 10.3 N/m. The object is set intooscillation with an initial potential energy of 0.150 J and aninitial kinetic energy of 6.90Ã—10^âˆ’2 J.
A) What is the amplitude of oscillation?
Express your answer with the appropriate units.
A=
B) What is the potential energy when the displacement isone-half the amplitude?
Express your answer with the appropriate units.
U=
C) At what displacement are the kinetic and potential energiesequal?
Express your answer with the appropriate units.
x=
D) What is the value of the phase angle Ï• if the initialvelocity is positive and the initial displacement is negative?
Express your answer in radians.
phi =
