Sector-specific technological measures – vapor recovery nozzles at gasoline pumps, cleaner-burning fuels, strong vehicle inspection programs and strict emission limits for refineries, industrial emissions and combustion sources – all can help control ozone pollution and have contributed to lower emissions over the last three decades

The number and units. An example would be 3cm or 4kg.
Answer:
95.78125%
18000 m/s
22233.33 seconds
Explanation:
t = Time taken
u = Initial velocity
v = Final velocity
s = Displacement
a = Acceleration
The velocity of the rocket at the end of the first 15 minutes is 18000 m/s which is the maximum speed of the rocket in the complete journey.
Distance traveled while speeding up
Distance traveled while slowing down
Distance traveled during constant speed
Fraction
Fraction of the total distance is traveled at constant speed is 95.78125%
Time taken at constant speed
Total time taken is 
Explanation:
here, u = 5m/s,a = 3m/s2, v = 23m/s, t = ?, s = ?
v = u+at
23 = 5 + 3t
t = 23- 5/3 = 18/3 = 6 sec
s= ut + 1/2 at ^2
s = 5 * 6 + 1/2 * 3 * (6)^2
s = 30 + 1/2 * 3 * 36
s = 30 + 18 * 3
s= 30 + 54 = 84 m
here, u = 0, a = x, t = 5min = 300 sec, s= 5.8km = 5800m
s = ut + 1/2 at^2
5800 = 0 * 300 + 1/2 * x * (300)^2
5800 = 1/2 * x * 90000
5800= 45000 x
x = 5800/45000
x = 0.12m/sec^2
here, v = 0, t = 6sec, s = ?, a = - 9.8m/s2
s = UT + 1/2 at ^2
s = 29.4 * 3 + 1/2 * - 9.8 * (3)^2
s= 88.2 - 44.1
s= 44.1 m
s = ut + 1/2 at ^2
s = 0 * 1 + 1*2 * 9.8 * (1)^2
s = 4.9m

Answer:
Personally I say the yellow truck but...
Explanation:
It's heavily based on the object's mass...
If you know which object has the most mass than I would choose that one, but personally I think the yellow one has the most mass...
