Answer:
B
Explanation:
if you sit up straight you will have a proper posture
It’d fall 29.4m or 96.46ft
Explanation:
Uhh since gravity is 9.8m/s then in three seconds it’d drop 29.4m or 96.46ft
That is assuming there isn’t a lot of wind resistance, but if you take that into account, then it’d probably be somewhere around 25m since the water bottle is going to be heavier than the wind resistance, and since we don’t know the weight of the water bottle it can’t really be calculated.
Hope this helps!
Answer:
686.11 N
1.7733 gallons
Explanation:
= Efficiency = 30%
V = Volume of gasoline
E = Energy content of gasoline = 
F = Force
s = Displacement = 108000 m
v = Velocity
Work done is given by

The force required to keep the car moving at a constant speed is 686.11 N
Here the force is directly proportional to speed



The gallons that will be used is 1.7733 gallons
I'm not sure of the numbers sense I dont have a calculator right now. The formula is 1/2*M*V^2.
