Acceleration = (change in speed) divided by (time for the change)
= (30 mile/hour) / (3 seconds) = (30 mile/hour x 5,280 feet/mile) / (3,600 sec/hour x 3 seconds)
= (30 x 5,280) / (3,600 x 3) = 14 and 2/3 feet per second2 = about 0.457 G
The answer depends on whether the rate of acceleration is uniform. There is no indication in the question that it is.
Constant velocity is a measure of distance traveled per unit of time at a uniform speed, such as miles per hour or feet per second. Constant acceleration is a measure of a continuing increase in velocity per unit of time, as when a car speeds up from 30 miles per hour to 40 miles per hour in 5 seconds, then from 40 miles per hour to 50 miles per hour during the next 5 seconds. It will then have had a constant acceleration of 10 miles per hour per 5 seconds.
There is no acceleration if the car is travelling at a steady 54,000 miles per hour.
Acceleration = change in velocity/change in time Acceleration = 96 miles per second - 32 miles per second/8 seconds = 8 miles per second per second or, better expressed 8 mi/s^2 ---------------
Acceleration = -20 mi/h^2
acceleration =(90-60)/(3)=10 mphs=10 mile per hour sec Ahmad Jordan

A thoroughbred can accelerate to 60 miles per hour in 5.5 seconds. They can reach 45 miles per hour in 2.5 seconds.

academic dishonesty
Acceleration = -20 mi/h^2
Acceleration = (change in speed) divided by (time for the change)Acceleration = (25 - 0)/(3) = 81/3 miles per second2Don't try this at home. That acceleration is about 1,368 G's. You can not survive it!
-66.667 miles per second squared
A gain of 2 miles per second squared
20 miles per second / 10 seconds = 2 miles per second ^ 2
