To determine the time it takes for the ball to return to the point it was thrown from, we first calculate the time it takes to reach the highest point. The total time for the ball to return will be twice that, since the time to go up equals the time to come back down.

The formula for time to reach the highest point is:

Where:

v₀ = 40 m/s (initial velocity)

g = 10 m/s²

Substituting the values:
