M is the mass. On the other hand you can change this problem around to find the mass or the acceleration of the object. Your velocity increases by 4 ms over a time period of 2 seconds so.
Now you start cycling faster.
Your speed changes by 2 meters per second per second. A is the acceleration. V BD u since OA u Equation 1 Now since the slope of a velocity-time graph is equal to acceleration a So a slope of line AB. A is the acceleration.
