To determine

To select: the correct option.

Answer to Problem 2STP

Option B. $50\text{ J}$

Explanation of Solution

In the graph, one small division along x-axis is taken to $\text{1s}$ and along y-axis is taken to be $200\text{ J}$

In the first one second, the corresponding kinetic energy is about a quarter of the one division, which is can be estimated as $50\text{ J}$ .

Conclusion:

Option B. $50\text{ J}$ is the correct answer.
