Aconstant unbalanced force is applied to an object for a period of time. which graph best represents the acceleration of the object as the function of elapsed time.

Here is an image attached with similar questions.

The correct answer is D where acceleration is function of time.

Explanation:

The force acting on the object is constant.

There is no change in the application of forces.

And we know that Force is the product of acceleration and masses.

Newtons second law:

Regarding mass we know that it can neither be created nor destroyed.

So in we have two constant terms, constant divided by constant will give the same result as

There is no change in acceleration with respect to time .

So the most appropriate graph where time (t) is changing on but acceleration doesn't changes is D.

The graph will be similar to and will be horizontal to the .

Option D depicts the same.

here we know that ball will drop down by total distance 3.2 m

so here we know that

now using kinematics

now in the same time it will cover horizontal distance of 0.75 m

so speed of the ball will be
