Answer:
1.52 hour
Explanation:
M = 0.5 g, I = 3 A
Electrochemical equivalent of nickel
Z = 3.04 × 10^(-4) g/C
By use of Faraday's laws of electrolysis
M = Z I t
t = M / Z I
t = 0.5 / (3.04 × 10^-4 × 3)
t = 5482.45 second = 1.52 hour
Let the time be t.
so,In time t , distance travelled by 1st cyclist = 12.6 t
distance travelled by 2nd cyclist = 9.2t + 0.5 (1.5) t^2
Now, cyclist 1st is already 11.4 m ahead of 2nd cyclist.
so, 9.2t + 0.5 (1.5) t^2 = 11.4 + 12.6t
find t :
t = 6.77 sec
The last one with the guy in the light yellow shirt
It would do exactly what a rock or a frisbee does when you toss it.
After the engines cut off, it couldn't get any more energy from
anywhere, and after that, as it pushed air aside to get through,
and had air molecules scraping against it, those would slowly
rob kinetic energy from it. Sooner or later it would run out of
kinetic energy, start falling, and it would eventually make either
a big 'SPLOOSH' or else a big 'CRUNCH', depending on exactly
where it returned to Earth's surface.
