Superman is flying 54.5 m/s when he sees a train about to fall into a river 850 m away. he reaches the train in 4.22 s. what is his final velocity?
Answers: 1
and 
where 
is distance, 
is the initial velocity, 
is the final velocity, 
is time, and 
is aceleration.
, and he will have to cover a distance d = 850m in a time t = 4.22s. Since we know 
.
