Simple harmonic motion is the motion in objects where the restoring for d is directly proportional to the body displacement.
<h3>What is simple harmonic motion?</h3>
Simple harmonic motion a type of periodic motion where the force that restores moving object to it's right position is directly proportional to the magnitude of body's displacement and this normally acts towards the object's equilibrium position.
The formulate for simple harmonic motion are
,F = −kx, where F is the force, x is the displacement, and k is a constanst. An example of a simple harmonic oscillator is the vibration of a mass attached to a vertical spring.
Simple harmonic oscillator can be represented by the equation x ( t ) = A cos ( 2 π f t ) x(t) = A\cos(2\pi f t) x(t)=Acos(2πft)x,
where t is period.
x is displacement
A is amplitude.

Answer:
Acceleration of the cart will be 
Explanation:
We have given force F = 40 N
Mass of the cart = 20 kg
From newton's second law we know that force, mass and acceleration are related to each other
From second law of motion force on any object moving with acceleration a is given by
F = ma, here m is mass and a is acceleration
So
