Assuming Earth's gravity, the formula for the flight of the particle is:
s(t) = -16t^2 + vt + s = -16t^2 + 144t + 160.
This has a maximum when t = -b/(2a) = -144/[2(-16)] = -144/(-32) = 9/2.
Therefore, the maximum height is s(9/2) = -16(9/2)^2 + 144(9/2) + 160 = 484 feet.
No, they do not have a pattern nor do they flow to get her the difference between 6 and 11 is 5, whereas the difference between 11 and 17 is 6.
3/5 of 30 is 90/5
3/5 of 30 is 18
so when it is 3/5 full then it has 18 gallons
Answer:
2 hours
Step-by-step explanation:
Train B's speed: 4/3 × 60 = 80
Combined speed = 80 + 60 = 120
Time = 240/120 = 2
