A car accelerates from rest to 25 m/s in 15 seconds. What is its acceleration?
Q1. A car accelerates from rest to 25 m/s in 15 seconds. What is its acceleration?
Answer: 7.5 m/s^2
Explanation: The acceleration of the car can be calculated using the formula a = Δv / Δt, where a is the acceleration, Δv is the change in velocity, and Δt is the time taken, giving an acceleration of 7.5 m/s^2.
