A ball is thrown vertically upwards with some speed. Then you can find the maximum height the ball travels above the ground. So final speed will be zero . b.cancer involves only certain kinds of cells and does not affect any other kind of cell. Answer;-Acceleration is constant -9.8m/s^2. (c) How long do. If a ball is thrown vertically upwards with speed u, the distance covered during the last t sec of its ascent is (1)ut (2)1/2gt (3)ut-1/2gt (4)(u+gt)t We have an Answer from Expert View Expert Answer (a) How high does it rise? Explanation;-An object that is thrown vertically upwards decelerates under the earth's gravity. If a ball is thrown vertically upward with an initial velocity of 160 ft / s, then its height after t seconds is s = 160 t 16 t 2. Assuming no air restance the speed when the ball comes back to the starting point will be again #8m/s# but directed DOWNWARDS; we can express this saying that it will equal to #-8m/s# adding a minus to indicate the downward direction. Last Post; Apr 24, 2020; Replies 12 for Class 9 2022 is part of Class 9 preparation. What will be its velocity at a height of 4.00 m (in m/s)? Grade 11.
