question 146

Short Answer

The graph in the figure shows the velocity of a particle as it travels along the x-axis. (a)In what direction (+x or -x)is the acceleration at t = 0.5 s?
(b)In what direction (+x or -x)is the acceleration at t = 3.0 s?
(c)What is the average acceleration of the particle between t = 2.0 s and t = 4.0 s?
(d)At what value of t is the instantaneous acceleration equal to 0 m/s²?
