Answer:
19.6 m
Explanation:
Total time of flight = 4.0 s ( given)
The time taken by gold ball to rise to the highest point = [tex]t=\frac{4.0 s}{2} = 2.0 s[/tex]
At highest point , final velocity would be = 0
Initial velocity can be calculated using the equation: v = u+at
⇒-u = -gt ⇒ u = gt
The distance to the highest point can be calculated as follows:
s = u t+0.5 at²
s = (gt)t +0.5 (-g)t²
s = 0.5 gt²
s = 0.5 (9.8)(2.0)²
s = 19.6 m
