A ball is dropped from rest and feels air resistance as it falls. Which of the graphs in ?Fig. Q5.25? best represents its acceleration as a function of time?
Solution 29DQ The graph of the acceleration of the ball as a function of time when it drops from the rest and feels air resistance as it fall is shown below.the correct graph is graph(d). The figure shows the velocity of a particle as it travels along the values of time is instantaneous acceleration is equal to zero.
