Question

Which equations can be used to solve for acceleration? Select four options.

t = delta v over a.
vf = at – vi
a = d over t.
vi = vf – at
v = a over t.
vf = at + vi
a = delta v over t.

Answer 1

Step-by-step explanation:

Acceleration of an object is calculated by finding the change in its velocity divided by time taken.

If
`v_i` is initial velocity,
`v_f` is final velocity and t is time taken. Then the acceleration of the object is given by :

`a=(v_f-v_i)/(t)\\\\at=v_f-v_i\\\\v_f=v_i+at` .....(1)

So, the above equation is used to find acceleration. It is called the first equation of motion. After rearranging equation (1), the correct options are :

`t=(\Delta v)/(a)`

`v_i=v_f-at`

`v_f=v_i+at`

`a=(\Delta v)/(t)`
