Expert Q&A Done Question How would the answer to part (b), the maximum height, change if the person throwing the ball jumped upward and let go of the ball at the same height as before the instant his feet lost contact with the ground? The maximum height would decrease. O The maximum height would remain the same O The maximum height would increase. PRACTICE IT Use the worked example above to help you solve this problem. A stone is thrown from the top of a building with an initial velocity of 20.4 m/s straight upward, at an initial height of 57.9 m above the ground. The stone just misses the edge of the roof on its way down, as shown in the figure. (a) Determine the time needed for the stone to reach its maximum height. 2.24 (b) Determine the maximum height. (c) Determine the time needed for the stone to return to the height from which it was thrown, and the velocity of the stone at that instant. Time Velocity m/s (d) Determine the time needed for the stone to reach the ground. (e) Determine the velocity and position of the stone at r = 6.78 s. Velocity m/s Position HINTS: GETTING STARTED I EXERCISE I'M STUCK! A projectile is launched straight up at 60.5 m/s from a height of 80.5 m, at the edge of a sheer cliff. The projectile falls just missing the cliff and hitting the ground below. (a) Find the maximum height of the projectile above the point of firing. (b) Find the time it takes to hit the ground at the base of the cliff. (c) Find its velocity at impact. m/s Need Help? Talk to a Tutor This is all one question, with sub questions. I'd appreciate the correct answers ASAP. I answered the 1st two and would appreciate confirmation on those. Much appreciated, Thanks Give me my question refund then.
