If a car goes from 20 miles per hour to 10 miles per hour in 5 seconds, Find its Acceleration.
We will be using the concept and formula for acceleration to solve this.
Answer: If a car goes from 20 miles per hour to 10 miles per hour in 5 seconds, its acceleration is -2 miles per hour.
Let's solve this step by step.
Explanation:
As we know, Acceleration = (final velocity - initial velocity)/time
Acceleration = (v - u)/t
Given that,
Final Velocity (v) = 10 miles per hour
Initial Velocity (u) = 20 miles per hour
Time (t) = 5 seconds
Acceleration = (10 - 20)/5
Acceleration = (-10)/5
Acceleration = -2 miles per hour.
