Question

An arrow is shot from the parapet of a castle and lands on the plain 35 meters below. If the arrow leaves the bow with a speed of 72 m/s, how fast is it traveling when it strikes the ground?

Answer 1

1/2 m v^2 + m g h = 1/2 m V^2

1/2 m 72^2 + m 9.8 35 = 1/2 m V^2

72^2 + (9.8 * 70) = V^2

Answer 2

Thanks so much :)
