The formula to find the final velocity , v , of an object having an initial velocity , u , and acceleration , a , at time t is v
8_murik_8 [283]

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.

a=\dfrac{v-u}{t}

(b) The relationship between the acceleration and time for a given initial and final velocity is given by "

s=ut+\dfrac{1}{2}at^2

Where

s is the distance covered

t is the time

Hence, this is the required solution.
