Question

A car is traveling in a straight line along a highway at a constant speed of 80 miles per hour for 10 seconds. Find the acceleration.​

Answer 1

8

Step-by-step explanation:

Because as you can see 80/10= 8

Answer is 8

Answer 2

The acceleration it's the difference of speed (final speed - initial speed) divided by the time. So:

a = Δv/t

In this case the initial speed is equal to 0. The final speed is equal to 80 miles/hour. The time is 10s.

a = 80 miles/hour divided by 10 = 8 miles/hour
