Answer:
Its acceleration is 1.5 and the distance it has covered is 150 m.
Explanation:
Acceleration is a quantity that indicates the variation in speed of a moving body as time passes. That is, acceleration relates changes in velocity with the time in which they occur.
The average acceleration is defined as the relationship between the variation or change in the speed of a mobile and the time used in said change:
In this case:
- change in speed= final speed - initial speed= 15 m/s - 0 m/s= 15 m/s
- time= 10 s
Replacing:
and solving you get:
<u><em>acceleration= 1.5 </em></u><u><em></em></u>
Speed is a quantity that expresses the relationship between the space traveled by an object and the time used for it. This is:
So the distance can be calculated as:
distance= speed* time
In this case:
- speed= 15 m/s
- time= 10 s
Replacing:
distance= 15 m/s* 10 s
and solving you get:
<u><em>distance= 150 m</em></u>
<u><em>Its acceleration is 1.5 </em></u><u><em> and the distance it has covered is 150 m.</em></u>
