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.

Hence, if a car goes from 20 miles per hour to 10 miles per hour in 5 seconds, its acceleration is -2 miles per hour.
