Chapter 3, Problem 2STP

To determine

The correct option.

Answer to Problem 2STP

The correct option is D.

Explanation of Solution

Introduction:

The object is in free fall state with the air resistance.

As observed from the graph the speed of the object is $20.1\text{m/s}$ (approximately) at time $5\text{s}$ .

As per first law of motion,every object remains at rest or in uniform motion untilforced to change it by the application of an external force.

The object will try to be at same speed after $5\text{s}$ until an external force is exerted. So, the most likely speed of the object after falling for $6\text{s}$ is nearly $20.1\text{m/s}$ (approximately).

Conclusion:

Hence, the correct option is C.
