3. An object thrown vertically upwards reached a maximum height of 5.0 m. Calculate:

(a) the velocity of the object when thrown

Ignore air resistance. [g = 9.81 m s-2]

Correct answer: V₀ = 9.9 m/s

Explanation:

The subject is a vertical upward shot.

We will use the following formula:

V₀² = 2 · g · h = > V₀ = √2 · g · h, where V₀ is initial velocity

V₀ = √2 · 9.81 · 5 = √ 10 · 9.81 = √98.1 = 9.9 m/s

V₀ = 9.9 m/s
