Question

A baseball is seen to pass upward by a window 24 m above the street with a vertical speed of 13m/s

If the ball was thrown from the street, when was it thrown?

t=???? s before passing the window

Answer 1

Answer #1

v² = v₀² + 2 a x

13² = v₀² + (2 * -9.8 * 24)

v₀ = 25.28 m/s

v = v₀ + a t

13 = 25.28 + (-9.8 * t)

t = 1.25 s
