What is the acceleration of a car that moves from a speed of 0 to 5 meters in 4.5 seconds?
Assume the car has constant acceleration a and initial velocity 0. Then the velocity at time t will be a*t, so if we call the distance travelled at time t, x, we get the following identity:
a*t = dx/dt
This differential equation can be solved in any number of ways to yield
1/2 * a * t^2 = x
where the constant of integration is zero since the distance travelled at time 0 is 0 by definition.
Therefore we have:
a = 2*x/t^2 = 2*5m/(4.5s)^2 = 40/81 ms^-2
or about half a meter per second squared

How much does its speed change after 5 minutes with an acceleration of 470 meters per second?
"470 meters per second" is a speed, not an acceleration. Assuming you mean "470 meters per second square", that is the same as a change of 470 meters per second every second. Just multiply by the number of seconds to get the change in speed."470 meters per second" is a speed, not an acceleration.

What is the distance traveled by an object that moves with an averace speed of 10 meters and 5 seconds?
Just divide the distance by the time. (In this case, the speed in the answer will be in meters per second.)
What is 60 meters in 3 seconds?
To find the speed, you can divide the distance by the time. If an object travels 60 meters in 3 seconds, its speed is 60 meters divided by 3 seconds, which equals 20 meters per second (m/s). This means the object moves at a constant speed of 20 m/s over that time interval.
What is a car's acceleration if it increases its speed from 5 meters per second to 20 meters per second in 3 seconds?
In general, the acceleration during that time interval could vary considerably. However, we can calculate the average acceleration during the interval. The change in speed is 20 meters per second - 5 meters per second = 15 meters per second, and this change in speed occurs over a 3 second interval. Thus the average change in speed over this interval is 15 meters per second/ 3 seconds = 5 meters per second per second = 5 meters/second2
