The velocity of an object is given by the equation vt 4t where the velocity v is measured in m s the time t is measured in seconds. So 1 ms is equal to 36 kmh. You still need the distance and you can get it this way.
To calculate velocity we calculate the displacement from the starting point to the finish point and divide that by the time covered.
V2-u22as v2 u2 2as. If you know how fast and how long something was traveling you can solve for the distance traveled. Now you have the time. This tells you how to find acceleration with velocity and distance.
