A small body is freely released from a platform located 605 meters above the ground. If g=10m/s2
and
we ignore air resistance find:

b) the velocity at the ground;
c) the
velocity at 425 m from the ground;
d) the distance traveled in the first 4 seconds of flight;
e) the distance
traveled in the last 4 seconds of flight;
f) the distance traveled in the third second of flight and in the
seventh.
 Relevant Equations:
 motion law, velocity law
Could you check if what I did is right and help me at e) and f)? Thank you!
