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.

    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=\dfrac{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=\dfrac{\Delta v}{a}

    v_i=v_f-at

    v_f=v_i+at

    a=\dfrac{\Delta v}{t}
