Explanation:
Remember that power is defined as how much Work is done per unit of time.
Work is defined as the amount of force applied across a certain distance.
Since in both cases of climbing the ladder (on Earth and the moon), Luke coveres the same amount of <em>distance </em>in the same amount of <em>time</em>, we are only left with one difference between the two cases - gravity.
If you were to carry your backpack on the moon with the same load of text books, it would take less force to pick it up on the moon. Therefore, Luke expends less effort on the environment with less gravity - the moon.
To find the difference factor - you would want to divid the gravitational contants between earth and the moon.
Hmmm, id say cardio.. but i don't know forsure
Answer:
a 10.6 m/s²
Explanation:
Since F = ma (Force = mass * acceleration), acceleration would be...
a = F/m
a = 302 N/28.6
a 10.6 m/s²
Answer:
Vw = 0.98m/s due 67.16° north of east
Explanation:
The distance the canoeist wants to travel is:
And the angle of the destination point is
With this trajectory and the time of 42s, we get the velocity of the canoe respect to ground:
Now we can calculate the velocity of the water:
