The acceleration of the car is 1.067 m/
.
<u>Explanation:</u>
Acceleration is the measure of change in velocity experienced by any object for a given time period. So it is determined as the ratio of difference in the velocity to the time period.
As here the initial velocity is stated as zero, so u = 0. And the final velocity is termed as 50 km/h. Then we have to determine the acceleration in 13 s. So here we have to convert the units as common units. Thus, 50 km/h should be converted to m/s as 
So now, the initial velocity u = 0 and final velocity v = 13.88 m/s and the time period is given as t = 13 s.

So the acceleration of the car is 1.067 m/

Its a solar cell. Photo voltaic Cell is also known as a solar cell.
<h3>I think it B The group(s) that gets the special treatment.</h3><h3 /><h3>I hope this is correct.</h3><h3 /><h3 /><h3 />
Let us assume that rocket only runs in initial energy and not using its own to flying.
Also , let upward direction is +ve and downward direction is -ve .
Initial velocity , u = 58.8 m/s .
Acceleration due to gravity ,
.
Final velocity , v - = 0 m/s .
We know , by equation of motion .

Hence, this is the required solution .
A believe that’s called a reference point.
