a block on a frictionless horizontal surface is attached to a spring (k=30 N/m). the mass is displaced to the right of equilibrium and released from rest. it travels a distance of 20 cm in 0.40 seconds before changing direction.
a. calculate amplitude of oscillations
b. calculate period of oscillation
c. calculate frequency of oscillations
d. derive formula for position of block as a function of time. only symbol allowed is 't'
e. calculate mass of block
f. max speed of block
g. max acceleration of block
