Well I figured out at his current pace, he would finish the 1100 remaining meters in 200 seconds. However, he needs to complete it in 180 seconds. I'm not sure how to find out how long he has to accelerate at 0.20 m/s/s to complete it in 180 seconds.
That's true. The only way to stop an object from radiating energy
is to cool it to absolute zero. Since the temperature of space is
roughly 3 degrees above absolute zero, the atoms or molecules
of every object have some kinetic energy, and the object radiates
some heat.
Of course it also absorbs heat at the same time, mostly from the
huge number of stars shining on it.
The distance and displacement are both zero.
If you took a photo of Jamie before she started spinning, and another one
after she finished spinning, you couldn't tell the difference in the photos.
Her center of mass never moved, and all of her motion produced no change
in her 'position' (location).
Answer:
It will take 20,000 seconds to get a pressure of 200Pa at the bottom of the tank.
Explanation:
The pressure at the bottom of the tank will be
where 
is the mass of the water, and 
is the base area of the tank.
The base area of the tank is
,
and if we want the pressure at the bottom to be 200pa, then it must be that
,
solving for we get:
which is the required mass of the water in the tank.
Now, the tank fills at a rate of 2 drops per second or
since each drop weights 0.05g.
Therefore, the time 
it takes to collect 20kg of water will be
which is 55.56 hours or 2 days and 7.56 hours.
Thus, it will take 20,000 seconds to get a pressure of 200Pa at the bottom of the tank.
Answer:
Friction acts in the opposite direction of the velocity. As static friction acts in the opposite direction to the acceleration. (opposite way)
