What is the skydiver velocity aftter one second show your work and include direction?

Assuming the skydiver starts at rest and accelerates at a rate of 9.8 m/s^2 due to gravity, the velocity after one second would be 9.8 m/s downward. This is because velocity is the initial velocity of 0 m/s plus the acceleration of 9.8 m/s^2 multiplied by 1 second.
