MULTIPLE CHOICE QUESTION

A block of mass 0.5kg on a horizontal surface is attached to a horizontal spring of negligible mass and spring constant 50N/m. The other end of the spring is attached to a wall, and there is negligible friction between the block and the horizontal surface. When the spring is unstretched, the block is located at x=0m. The block is then pulled to x=0.3m
and released from rest so that the block-spring system oscillates between x=−0.3m and x=0.3m. What is the magnitude of the acceleration of the block and the direction of the net force exerted on the block when it is located at x=0.3m?

What is the defining equation for simple harmonic motion?
x(t) = A * cos(ωt - φ)
x(t) = A * cos(ωt + φ)
x(t) = A * sin(ωt + φ)
x(t) = A * tan(ωt + φ)
