Step-by-step explanation:
The formula to find the final velocity, v of an object having an initial velocity , u , and acceleration , a , at time t is v=u+at
(a) v=u+at
Subtract u from both sides,
v-u=u+at-u
v-u=at
Dividing both sides by t.
[tex]a=\dfrac{v-u}{t}[/tex]
(b) The relationship between the acceleration and time for a given initial and final velocity is given by "
[tex]s=ut+\dfrac{1}{2}at^2[/tex]
Where
s is the distance covered
t is the time
Hence, this is the required solution.
