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.

The base of a 50-meter tower is at the origin; the base of a 50-meter tree is at (0, 50, 0). the ground is flat and the z-axis points upward. the following parametric equations describe the motion of six projectiles each launched at time t = 0 in seconds. (i) r (t) = (50 + t2)k (ii) r (t) = 2t2 j + 2t2k (iii) r (t) = 50 i + 50 j + (50 β t2)k (iv) r (t) = 2t j + (50 β t2)k (v) r (t) = (50 β 2t) i + 2t j + (50 β t)k (vi) r (t) = t i + t j + tk (a) which projectile is launched from the top of the tower and goes downward? at time t = , the projectile hits the ground at point (x, y, z) = . (b) which projectile hits the top of the tree?
