Given that the ball is thrown into the air and follows the parabolic path shown, let's use the given arrows to indicate the approximate directions of the velcoity and acceleration of the ball at each of the three loctaions neglecting air resistance.
Since the ball was thrown in air and follows the parabolic path, neglecting air resistance, the acceleration will always act downward.
Hence, the acceleration at the three locations will be pointing downwards.
• The velocity at the first location is will be pointing in the North-east direction:
• The velocity at the second location will be pointing towards the right:
The velocity at the third location will be pointing in the South-East direction:
Therefore, we have:
