An archer shoots an arrow straight up into the air with an initial velocity of 45 m/s . Calculate the maximum height of the arrow.(adsbygoogle = window.adsbygoogle || []).push({});

The equation I would use for this is:

Vf^2 = Vo^2+2as

where:

Vf is final velocity

Vo is initial velocity

a is acceleration (gravity)

s is displacement

plug in the numbers we know:

0^2 = 45^2 + 2(-9.8)s

now solve for s

0=2025-19.6s

-2025=-19.6s

s = 103.32 meters.

is this right
