Question
A car at rest accelerated to 60 km/h in .6 hours. What is its acceleration? a100 km/h b-100 km/h c36 km/h d-36 km/h
Solution
To calculate acceleration, we need to use the formula:
Acceleration = (Final velocity - Initial velocity) / Time
Given in the problem: Final velocity = 60 km/h Initial velocity = 0 (since the car was at rest) Time = 0.6 hours
Substitute these values into the formula:
Acceleration = (60 km/h - 0) / 0.6 hours = 100 km/h^2
So, the acceleration of the car is 100 km/h^2. Therefore, the correct answer is a) 100 km/h.
