Answer:
The final position made with the vertical is 2.77 m.
Explanation:
Given;
initial velocity of the ball, V = 17 m/s
angle of projection, θ = 30⁰
time of motion, t = 1.3 s
The vertical component of the velocity is calculated as;

The final position made with the vertical (Yf) after 1.3 seconds is calculated as;

Therefore, the final position made with the vertical is 2.77 m.
