As the kid rises to a height of 0.925 meters, his velocity decreases at the rate of 9.8 m/s each second. At the maximum height, his velocity is 0 m/s. Use the following equation to solve this problem.
vf^2 = vi^2 + 2 * a * d, vf = 0, a = -9.8 0 = vi^2 + 2 * -9.8 * 0.925 vi = √18.13 This is approximately 4.26 m/s.
I hope this helps, have a great day, and God bless. Brainliest is always appreciated :)
