You toss a ball straight upward, in the positive direction. The ball falls freely under the influence of gravity.
At the highest point in the ball’s motion,
its velocity is zero and its acceleration is zero.
its velocity is zero and its acceleration is positive (upward).
its velocity is zero and its acceleration is negative (downward).
its velocity is positive (upward) and its acceleration is zero.
its velocity is positive (upward) and its acceleration is zero.
This is a motion diagram of an object moving along the x-direction with constant acceleration. The dots 1, 2, 3, … show the position of the object at equal time intervals ∆t. Which of the following vx-tgraphs best matches the motion shown in the motion diagram?
Which of the following ax–t graphs (graphs of acceleration vs. time)best matches the motion of the glider as it goes down?
