You throw a ball vertically upward so that it leaves the ground with velocity 5.68 m/s.
(a) What is its velocity when it reaches its maximum altitude? magnitude 0 Correct: Your answer is correct. m/s direction Incorrect: Your answer is incorrect.
(b) What is its acceleration at this point? magnitude -9.8 Incorrect: Your answer is incorrect. The response you submitted has the wrong sign. m/s2 direction Incorrect: Your answer is incorrect.
(c) What is the velocity with which it returns to ground level? magnitude -5.68 Incorrect: Your answer is incorrect. The response you submitted has the wrong sign. m/s direction Correct: Your answer is correct.
(d) What is its acceleration at this point? magnitude 9.8 Correct: Your answer is correct. m/s2 direction Correct: Your answer is correct.
