Explanation:
velocity: average velocity equals Displacement /change in time.
Kinetic energy: K=1/2mv^2 (m = Mass) ( v = Velocity).
speed using the kinetic energy is also KE =1/2mv^2
(M in Kg) (V in m/s)
Answer:

Explanation:
Kinematics equation for constant acceleration:

C. fly in a straight line unless an outside force changes its course.
