If the bob is replaced by one of mass 4m, the period of oscillation is
T
Which of the following is true for a system consisting of a mass oscillating on the
end of an ideal spring?

equilibrium position
A 0.1 kilogram block is attached to an initially unstretched spring of force
constant k = 40 newtons per meter as shown above. The block is released from
rest at time t=0.
What is the amplitude of the resulting simple harmonic motion of the block?
1/40 m
A 0.1 kilogram block is attached to an initially unstretched spring of force
constant k = 40 newtons per meter as shown above. The block is released from
rest at time t=0.
At what time after release will the block first return to its initial position?
pi/10 s
