Question

10. You throw a ball straight down off the Empire State Building. It takes the ball 22 seconds to land. Ignore air resistance. What speed did you throw the ball? (search height of Empire State Building)​

Answer 1

vi = -87.66 m/s

Step-by-step explanation:

Height of Empire State Building = 443 m

t = 22 s

y = (vi)(t) + (1/2)(g)(t²),

443 = (vi)(22) + (1/2)(-9.8)(22²),

vi = -87.66 m/s
