The answer is -36 m/s.
Final velocity= initial velocity + acceleration x time
7 + (-9.8) (3) = -36.4 m/s
What is velocity?
Velocity is the directional speed of an object in motion as an indication of its rate of change in position as observed from a particular frame of reference and as measured by a particular standard of time.
What are velocity and acceleration?
Instantaneous velocity refers to an object's velocity at an exact moment in time. Acceleration is the change in the velocity of an object, either as it increases or decreases. Acceleration is also a vector and will have both a value and a direction.
