The speed of the ball 0.60 seconds after it is released is 6.8 m/s.

Newton's law of motion is given by:

v = u + gt

where v is the final velocity, u is the initial velocity, g is the acceleration due to gravity and t is the time.

Given that:

u = 0.8 m/s, g = 10 m/s², t = 0.6s. Hence:

v = 0.8 + 10(0.6)

v = 6.8 m/s

Therefore the speed of the ball 0.60 seconds after it is released is 6.8 m/s.
