Both Theodore Roosevelt & Woodrow Wilson. <span />
1) Type of motion: constant acceleration.
2) acceleration, a = 9.8 m/s^2
3) time up = time down = 4seconds / 2 = 2 seconds
4) formula = Vf = Vo - a*t^2/2
Vf = 0 => Vo = a*t^2 / 2 = 9.8m/s^2 * (2 s)^2 / 2 = 19.6 m/s
Answer: 19.6 m/s
The answer is C. is right
Answer:
3, 15
Step-by-step explanation:
1/10 of a unit also just means dividing by 10. 1/2 is just dividing by 2. Hope this helped!
