Question

Car P takes 2 seconds to reach 100 km/h , whereas car Q takes 2.2 seconds for the same. Both the cars start from rest. Which car accelerated more?​

Answer 1

Answer:

Car P accelerated more

Explanation:

We know a=∆v/∆t ( acceleration= change in velocity/time taken)

As in the above both cases, ∆v is same (100) .

Taking v constant in the above formula, it becomes

a∝ 1/t. which means less time and more acceleration.

So car P takes less time and hence has more acceleration.
