a) A ball is thrown straight up in the vertical direction with an initial velocity of 12.0 m/s. Suppose the ball starts at the ground level. If we ignore the air resistance, what is the maximum height that the ball will reach, and what is the final velocity of the ball (magnitude and direction) when it comes back to the ground level? If the air resistance were not negligible, how would the maximum height and the final velocity at the ground level be affected? (3 points) b) If this ball is kicked from the ground with an initial velocity of 16.0 m/s in the horizontal direction and 12.0 m/s in the vertical direction. Ignore the air resistance, at what velocity (magnitude and direction) does the ball hit the ground? (2 points) c) If instead of kicking the ball from the ground, the player stands on a platform of 0.5 meter higher than the ground level and kick the ball with the same initial velocity (16.0 m/s in the horizontal direction and 12.0 m/s in the vertical direction). Ignore the air resistance, at what velocity (magnitude and direction) does the ball hit the ground?
