V1
A mass of 0.50 kg is in harmonic horizontal friction-free oscillation with a spring. The
oscillations cover a total distance of 0.500 m. The oscillation can be described by the formula
x(t) = Acos(@t+). The acceleration is ax= -0.60 m/s² when the mass is at x = 0.020 m.
wwwwwwwww
m = 0.50 kg
x
x = 0 x = 0.020 m
a) What is the phase angle if x=0.14 m at t=0 s? (1 p)
b) What is the spring constant ? (2 p)
c) What is the kinetic energy at x = 0.14 m? (1 p)
