The answer to number five is: -1
the answer to number six is that adding a negative to a negative is the same as adding positives because either way you are getting rid of the negatives.
Based on the calculations, Mohammed's acceleration is equal to 0.2 .
<u>Given the following data:</u>
- Initial time = 3.0 seconds.
- Initial velocity = 1.2 m/s.
- Final time = 7.0 seconds.
- Final velocity = 2.0 m/s.
To determine Mohammed's acceleration:
<h3>How to calculate acceleration.</h3>
In Science, the average acceleration of an object is calculated by subtracting its initial velocity from the final velocity and then dividing by change in time for the interval.
Mathematically, average acceleration is given by this formula:
<u>Where:</u>
- U is the initial velocity.
- is the initial time measured in seconds.
- is the final time measured in seconds.
Substituting the given parameters into the formula, we have;
Acceleration, a = 0.2
