Acceleration = Change in Velocity over time
a = (v-v0)/t
In this case, v = 60 mph and t = 6 s
So a = (60mph)/(6s) which is 10 miles per hour per second. (This is 36000 miles per hour per hour, or 36,000 miles per hour squared [36000 m/h2.)
well 40 miles per hour means that a car goes 40 miles in one hour... so if a car is going 80 miles in one hour and you divide the 80 and one hour by 2.. then you get 40 miles in 30 minures.. and the car is going 80 miles per hour.
It really depends on the speed of which the car is moving. If its speed is 40 miles/hour, it will take one hour to go 40 miles.
a pickup can travel 300 miles in the same time that a car going 10 miles per hour faster can travel 350 miles. How fast is the car traveling?
55 miles per hour.
5 metres per second squared
There is no acceleration if the car is travelling at a steady 54,000 miles per hour.
Acceleration = -20 mi/h^2

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.
acceleration =(90-60)/(3)=10 mphs=10 mile per hour sec Ahmad Jordan
The answer depends on whether the rate of acceleration is uniform. There is no indication in the question that it is.
(1 mile / 75 seconds) x (3,600 seconds / hour) = 48 miles per hour
9.167 miles per second a = s2- s1/t = 55-0/6 = 9.167
The car is slowing down at a rate of 10 miles per hour for each hour it continues this rate.
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
