Best Answer

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

What is the average speed of a car that speeds up from 60 miles per hour to 70 miles per hour in 8 seconds?

The answer depends on whether the rate of acceleration is uniform. There is no indication in the question that it is.


How does constant velocity differ from constant acceleration?

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.


What is the acceleration of a car traveling from 0 to 60 miles in 4 seconds?

What is the acceleration of a car that goes from 32 miles per second to 96 miles per second in 8 seconds?

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 ---------------

What is the acceleration of a car that goes form 0 miles per second to 25 miles per second in 3 seconds?

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!
