If a skydiver has a forward velocity of 40 m/s, what is the forward velocity after one second?

Question

What is the downward velocity after one second?

Answer 1

There is no horizontal force (ignoring air friction) so the horizontal velocity remains 40 m/s

In the vertical direction there will be acceleration down of about 9.81 m/s
If the original vertical speed was zero, after one second it will be 9.81 t = 9.81 m/s down
