Acceleration from Velocity
This applet displays graphs of velocity of an object as a function of time, with a point emphasized. If the velocity graph is curved, the tangent line is also shown. Your task is to calculate the instantaneous acceleration of the object at that point. Remember that the instantaneous acceleration at any given time is the slope of the velocity curve at that time. You need to put a space between the number and the unit in your answer. (You may want to review the demonstration of the analogous calculation of the velocity of an object from its position graph.)
