The position of a 50 g oscillating mass is given by x(t)=(2.0cm)cos(10t−π/4), where t is in s. If necessary, round your answers to three significant figures. Determine:

a) amplitude cm

b) the period s

c) the spring constant N/m

d) the phase constant rad

e) the initial coordinate of the mass cm

f) the initial velocity cm/s

g) the maximum speed cm/s

h) the total energy mJ

i) the velocity at t=0.40 s cm/s
