A v vs. t graph is drawn for a ball moving in one direction. The graph starts at the origin and at t = 5 s the acceleration of the ball is zero. We know that at t = 5 s,
 a. the slope of the curve is non-zero.
  b. the velocity of the ball is not changing.
  c. the curve is not crossing the time axis.
  d. the curve is at v = 0, t = 0.

Question 2

An x vs. t graph is drawn for a ball moving in one direction. The graph starts at the origin and at t = 5 s the velocity of the ball is zero. We can be positive that at t = 5 s,
 a. the slope of the curve is non-zero.
  b. the ball has stopped.
  c. the acceleration is constant.
  d. the curve is at x = 0, t = 0.
