Answer:
Correct answer is: t = 0.8 seconds
Explanation:
This movement is a vertical shot upwards, the formula is:
V = V₀ - g t , where V₀ is the initial velocity and V is the final velocity
when the ball reaches its highest point the final velocity V is equals to zero
then it is:
V₀ = g t if we get g = 10 m/s²
t = V₀ / g = 8 / 10 = 0.8 seconds
t = 0.8 seconds
