Answer:
Step-by-step explanation:
For obects already in motion, the distance travelled, s, is:
s = vi*t + (1/2)at^2
where vi is the initial velocity, a is the acceleration, and t is the time in seconds.
We want the time, t, to reach 1000 meters.
1000 m = (3 m/s)*t + (1/2)*(0.1m/s^2)*(t^2)
(1/2)*(0.1m/s^2)*(t^2) = 0.05t^2
0.05t^2 + 3t -1000 = 0
Solve quadratic equation:
t = 114.6 seconds
Answer:
A
Step-by-step explanation:
![h(t)-j(t)=t^{\frac{2}{3}}-9-[3t+5t^{\frac{2}{3}}]\\\\=t^{\frac{2}{3}}-9-3t-5t^{\frac{2}{3}}\\\\=t^{\frac{2}{3}}-5t^{\frac{2}{3}}-3t-9\\\\=[1-5]*t^{\frac{2}{3}}-3t-9\\\\=-4t^{\frac{2}{3}}-3t-9](https://tex.z-dn.net/?f=h%28t%29-j%28t%29%3Dt%5E%7B%5Cfrac%7B2%7D%7B3%7D%7D-9-%5B3t%2B5t%5E%7B%5Cfrac%7B2%7D%7B3%7D%7D%5D%5C%5C%5C%5C%3Dt%5E%7B%5Cfrac%7B2%7D%7B3%7D%7D-9-3t-5t%5E%7B%5Cfrac%7B2%7D%7B3%7D%7D%5C%5C%5C%5C%3Dt%5E%7B%5Cfrac%7B2%7D%7B3%7D%7D-5t%5E%7B%5Cfrac%7B2%7D%7B3%7D%7D-3t-9%5C%5C%5C%5C%3D%5B1-5%5D%2At%5E%7B%5Cfrac%7B2%7D%7B3%7D%7D-3t-9%5C%5C%5C%5C%3D-4t%5E%7B%5Cfrac%7B2%7D%7B3%7D%7D-3t-9)
7.6x = 64
7.6/7.6
Therfore, x = 64/7.16
x = 8.938
