A ball is tossed straight upward from ground level. A student chooses downward as the positive y-direction. Which of the following lists the signs of the ball’s velocity and acceleration at the instant the ball reaches its highest point?
(a) Velocity = 0\,m/s, Acceleration = 0
(b) Velocity = positive, Acceleration = positive
(c) Velocity = 0\,m/s, Acceleration = positive
(d) Velocity = 0\,m/s, Acceleration = negative
