You throw a ball straight up with an initial speed of 23.5 m/s. What is the maximum height the ball will reach?
also, How long is the ball in the air before it reaches its maximum height?
if a ball is thrown upwards it will have 0 velocity at maximum height and its gonna fall back.
formula: here a = acceleration due to gravity = g = 9.8m/s2
v2 - u 2 = 2 a s
0 - (23.5)^2 = 2 X 9.8 X h
-552.25 = 19.6 X h
h = -552.25/19.6 = -28.17 m = 28.17m
dont worry about the negative sign. This is because the acceleration is against the direction of velocity. that means the particle is decelerating.
