(D : There is one problem with 5 parts; see the back of the page. Note: Here are some simple equations which may, or may not, be useful. w=21r/T=27rf; a=—w2a:=F/M; wzzg/L Note: This is a SHOWWORK problem; you must show your work to
earn credit; you can earn partial credit. A 0.90 kg mass on an ideal (frictionless) spring is in simple harmonic motion with
displacement :1: = 0.400%(4.6t+1r/2), where a: is measured in meters and t is measured
in seconds. a) Find It, the value of the spring constant. [3] 31:070.: ~b< ) Q’s"W ska/27701
