Step-by-step explanation:
28 m/s is the velocity , when it is going after 4.0 seconds.
When a point or an object moving in a straight line , the acceleration is the rate at which velocity changes with time, in terms of both speed and direction.
Here, given that,
A car is moving at a constant acceleration of 7.0 m/s/s
Now, we have,
Velocity = acceleration * time
After 4 sec. = 7*4 = 28 m/s
Hence, 28 m/s is the velocity , when it is going after 4.0 seconds.

The unit rate of the copy machine expressed in terms of copies per second is found by calculating the ratio 45 copies/25 seconds, which equals 1.8 copies/second.
To find the unit rate of copies per second, we need to divide the total number of copies by the total time taken. In other words, we have to find out how many copies are made in one second. Here, the copy machine makes 45 copies in 25 seconds.
To calculate the unit rate, we use the formula Unit Rate = Total Quantity / Total Time. Substituting the given numbers into the formula, we get:
Unit Rate = 45 copies / 25 seconds = 1.8 copies/second.
This means the copier's unit rate is 1.8 copies per second.
