A ball is thrown under the influence of gravity alone so that it is projectile motion. The trajectory and several positions of the ball are shown.
Use a ruler and draw accurate vectors and vector components.
(a) Draw a vector showing the horizontal component of the velocity at each location.
(b) Draw a vector showing the velocity of the ball at each location.
(c) Draw a vector showing the acceleration of the ball at each location--use a double shafted arrow (=====>).
(d) As the ball is moving up, what is the angle between the velocity and the acceleration, < 90°, = 90° or > 90°?
(g) When the ball is at maximum height, what is the angle between the velocity and the acceleration, < 90°, = 90° or > 90°?
(f) As the ball is moving down, what is the angle between the velocity and the acceleration, < 90°, = 90° or > 90°?
