Answer :

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
