Problem data: m (ball mass) = 500 g (in SI m = 0.5 kg); F (force of impact on the ball) = 300 N; V (the speed at which the ball was sent) = 60 m / s.
The duration of the flight of the ball can be expressed from the equality: m * V = F * t, whence t = m * V / F.
Let’s make a calculation: t = 0.5 * 60/300 = 0.1 s.
Answer: The duration of the flight of the ball is 0.1 s.
