Afew years ago, serena williams dived to hit a tennis ball right after it bounced off the ground. the ball bounced on the ground 11.5 m from the net, and after serena hit the ball it flew over the 0.950 m high net and bounced in her opponent's court about 1.05 s after she hit it. if there had been no gravity, the ball would have been 1.73 m higher than the net when it crossed over.. how fast was the ball moving when it left serena\'s racket? ignore any effects from ball spin and air resistance.

as technology advances, new experiments often expose problems in accepted theories. c

d₁ = displacement of tern from arctic to antarctic = 11000 miles

d₂ = displacement of tern from antarctic to arctic =   - 11000 miles

d = total displacement for the journey

total displacement for the journey is given as

d = d₁ + d₂

d = 11000 + (-11000)

d = 0 miles

t₁ = time of travel from arctic to antarctic = 3 months = 3 x 30 days = 90 days

t₂ = time of travel from antarctic to arctic = 3 months = 3 x 30 days = 90 days

t = total time of travel

total time of travel is given as

t = t₁ + t₂

t = 90 + 90

t = 180 days

average velocity is given as

average velocity = total displacement/ total time

v = d/t

v = 0/180

v = 0 miles/day
