Question

You are trying to get a kite out of a tree by throwing another ball at it. The kite is 13.2 m high. Assuming you have great accuracy, what initial velocity is required to hit the kite?

Answer 1

16.1 m/s

Step-by-step explanation:

Given:

Δy = 13.2 m

v = 0 m/s

a = -9.8 m/s²

Find: v₀

v² = v₀² + 2aΔy

(0 m/s)² = v₀² + 2 (-9.8 m/s²) (13.2 m)

v₀ = 16.1 m/s
