Question

In a 100 m race between Ramesh and Suresh, Ramesh wins the race. Assuming they run with uniform acceleration. Which of the following is correct?

• A. Acceleration of Suresh is more than Ramesh
• B. Acceleration of Ramesh is more than Suresh
• C. Both Suresh and Ramesh have equal acceleration
• D. Both Suresh and Ramesh have equal average

Answer 1

The correct option is B

Acceleration of Ramesh is more than Suresh

Correct Answer: option(b)

Step 1: Given Data

1. A 100 m race occurred between Ramesh and Suresh.
2. Both of them move with uniform acceleration which means acceleration does not change with change in time.
3. Ramesh wins the race.

Step 2: Explanation for the correct option

1. We know acceleration is defined as the rate of change of speed with time. So$acceleration=\frac{speed}{time}$.
2. If we consider speed is the same for both of them then the acceleration will be inversely proportional to time. So$acceleration\propto \frac{1}{time}$.
3. So we can say that the person who takes less time to cover the distance will have more acceleration.
4. As Ramesh wins the race, he takes less time to cover that distance. So the acceleration of Ramesh is more than that of Suresh.

The acceleration of Ramesh is more than that of Suresh.
