How can you change the initial conditions so that the block does not oscillate in a plane? Select all that will work.
a. Displace the block to the side and give the block an initial velocity in a direction out of the plane defined by the equilibrium position, the support point and this initial position (recall that three points define a plane).
b. Displace the block to the side and give the block an initial velocity in a direction in the plane defined by the equilibrium position, the support point and this initial position (recall that three points define a plane).
c. Start the block at the equilibrium position, but give it an initial velocity.
