1.An apple weighs 1.00 N.When you hang it from the end of long spring of force constant k = 2.00 N/m and negligible mass, it bounces up and down in SHM.If you stop the bouncing and let the apple swing from side to side through s small angle, the frequency of this motion is half the bounce frequency.What is the un-stretched length of the spring?

2.An object vibrating in simple harmonic motion has am amplitude of 5 cm and a period of 1.2 s.How long does it take for this object to move 2 cm from the maximum displacement of 5 cm?
