"with what velocity did it strike the water?"
final velocity = initial velocity+ (acceleration * time)
initial velocity is zero because it fell off a bridge.
acceleration is 9.8 (gravity) because it was falling.
time is 3.03
0 + (3.03 x 9.8) = final velocity
the average velocity is your final velocity plus your initial velocity divided by 2
which is just your final velocity divided by 2 because your initial velocity was zero.
how high is the bridge?
distance the object fell= average velocity x time
an object is observed to fall from a bridge, striking the water below 3.03s ...with what velocitydid it strike the water?what was the average velocity during the fall?how high is the bridge?

thank you very much
why u divide the final velocity by 2?
ahaaaaaa i understand
could u give me the answers for check please
