Question

The final velocity of an object moving in one dimension is given by the formula v = x + at, where u is the

initial velocity, a is the acceleration, and t is the time.
Solve this equation for a.
a = (v + U)/
a = t(v + U)
a =t(v - u)
a = (v – u)/t

Answer 1

Acceleration,
`a=(v-u)/(t)`

Explanation:

The final velocity of an object moving in one dimension is given by the following formula as :

`v=u+at`...........(1)

where

u is the initial velocity

a is the acceleration

t is the time taken

We need to solve equation (1) to find the value of a. Subtracting u on both sides of the equation :

`v-u=at`

Now divide both side of the equation by t as :

`a=(v-u)/(t)`

So, the correct option is (d).

Answer 2

a = (v – u)/t

Explanation:

We know,

v = u+ at

v-u=at

(v-u) /t=a
