A particle travels according to the following velocity function. Therefore the only time that speed is the same as velocity is when the object travels in a straight line. U frac s t-frac 1 2at.
To calculate velocity we calculate the displacement from the starting point to the finish point and divide that by the time covered.
Therefore the only time that speed is the same as velocity is when the object travels in a straight line. The equation above can be used to calculate the final velocity of an object if its initial velocity acceleration and displacement are known. V is the velocity. An object with a final velocity of 3 meters 98 ft traveled south for 15 seconds and covered a distance of 45 meters 1476 ft.
