Question

When divided by △t, (vf - vi) is used to determine which characteristic? A.Speed B.Direction C. Displacement D.Acceleration

Answer 1

D.Acceleration

Step-by-step explanation:

The acceleration of an object is defined as:

`a=(v_f -v_i)/(\Delta t)`

where

vf is the final velocity of the object

vi is the initial velocity of the object

`\Delta t` is the time taken for the change in velocity to occur

Therefore, from the formula, we see that if we divide (vf - vi) by △t, we get the acceleration.
