10 seconds
sqrt(30) seconds = 5.48 seconds (approx)
30m/s
Just under 60 psi at 30m
No
The work done against the resistive force is 30N * 30m = 900 J. Since work is done in 6 seconds, the power exerted by the cyclist is 900 J / 6 s = 150 Watts.
30m
The GCF of 12m, 15m and 30m is 3m.
200
30m (meters) is 98.425 feet or 16.4 fathoms.
30m = 3000cm, so there are 1000 lots of 3cm in 30m
50m/30m = 50/30 = 5/3
