# The ball is thrown vertically upwards at a speed of 5 m / s. How long will it take to reach the top?

June 27, 2021 | education

| When moving in a straight line, the speed of the ball can be calculated using the formula:

V = V0 + at, where V is the final speed of the ball (V = 0 m / s, since the ball stopped), V0 is the initial speed of the ball (V0 = 5 m / s), and is the acceleration of the body (a = -g = -10 m / s ^ 2, the movement of the ball is equally slow), t is the time of movement (s).

Let’s express and calculate the time of the ball movement:

0 = V0 – gt; V0 = gt.

t = V0 / g = 5/10 = 0.5 s.

Answer: The ball will reach the top point in 0.5 seconds.
