The Graph in the Figure Shows the Velocity of a Particle

question 136

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?
