Question

A ball is launched vertically at 60m/s. how long until it reaches maximum height?

Answer 1

Step-by-step explanation:

At the maximum height, the velocity is 0.

Given:

v₀ = 60 m/s

v = 0 m/s

a = -9.8 m/s²

Find: t

v = at + v₀

(0 m/s) = (-9.8 m/s²) t + (60 m/s)

t = 6.1 s

Round as needed.
