Answer :
Answer:
1.29 m
Explanation:
mass of ball = 0.6 kg
initial velocity, u = 8.7 m/s
final velocity, v = 7.1 m/s
acceleration due to gravity, g = - 9.8 m/s^2
(a) Let the ball reaches to a height of h.
Use third equation of motion
[tex]v^{2}=u^{2}+2as[/tex]
[tex]7.1^{2}=8.7^{2}- 2 \times 9.8 \times h[/tex]
h = 1.29 m
Thus, the maximum height attained by the ball is 1.29 m.
