Question 12 POST_UTME_MADONNA_UNIVERSITY • 2018 • PHYSICS • objective

A block of mass $M$ is placed on a frictionless surface and connected to a spring with spring cons\tant $k$. The block is then displaced from its equilibrium position by a dis\tance $x_0$ and released from rest. Assuming the motion is simple harmonic, find the force exerted by the spring on the block as a function of time $t$.

Answer Options

Correct Answer A. F = -kx = -kA\cos\omega t
B. F = -kx = kA\sin\omega t
C. F = -kx = kA\cos\omega t
D. F = -kx = -kA\sin\omega t
Correct Answer
A
Correct Option:
F = -kx = -kA\cos\omega t
