Question

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.Rearrange the formula to find the acceleration

B. Using the formula in part A describe the relationship between the acceleration and time for a given initial and final velocity

Answer 1

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=(v-u)/(t)`

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

`s=ut+(1)/(2)at^2`

Where

s is the distance covered

t is the time

Hence, this is the required solution.
