You need to convert the 4 hr 7 min 29 s all to the same unit to start off with, the best thing to do usually is to convert to the smallest unit so we convert to seconds:
29s = 29s, no need to change anything there
7min = 7 X 60s = 420s
4h = 4 X 60min = 240min, 240 X 60s = 14,400s
Now that we've converted all the time units to the same unit (seconds), we add them together:
29 + 420 + 14,400 = 14,849s
Generally when we talk about speed and are using seconds as our unit for time, we express speed in m/s (metres per second), so now we convert the kilometres to metres:
1 km = 1000 m, so 42.2 km = 42.2 X 1000 = 42,200m
Finally, we can use our formula:
42,200 / 14,849 = 2.841942218 m/s
(I kind of rushed the calculations a little bit so that figure may not be 100% accurate, but the method is definitely correct)
Hope this helped :)
Answer:
As a sample of matter is continually cooled, the average kinetic energy of its particles decreases. Eventually, one would expect the particles to stop moving completely. Absolute zero is the temperature at which the motion of particles theoretically ceases.
