A ball is tossed up into the air with a velocity of 50 m/s. The figure to the left shows the position of the ball at equal time intervals on its upward travel. Answer the following questions regarding the instantaneous velocity and acceleration of the ball: a. The velocity of the ball has decreased from point B to point C.     (True/ False/ Insufficient Information) b.  Where does the ball have the smallest velocity?    (Position A/ PositionB/ Position C/ Position D/ Insufficient Information ) c. What is the direction of the acceleration of the ball at point A?    (Up/ Down/ There is no acceleration/ Insufficient Information ) d. The acceleration and velocity of the ball both are upwards at point A.   (True/ False/ Insufficient Information)
