How fast must a person lift a barbell with a weight of 635 N to a height of 2.43 meters in order to have a power of 482 W
Answer:
Time = 3.2 seconds
Explanation:
Given the following data;
Weight = 635 N
Height, h = 2.43 m
Power = 482 Watts
To find the time;
Power = mgh/time
But weight = mg = 635
Substituting into the formula, we have;
482 = (635 * 2.43)/time
482 = 1543.05/time
Time = 1543.05/482
Time = 3.2 seconds

the moon doesn't fall to earth because of it's friction?
Answer:
The Moon does not fall towards Earth right now because Earth rotates itself. The energy from the Earth's own rotation around its axis is gradually tranferred into energy of the Moon's orbital motion. That's why the Earth's rotating speed decreases but the distance to the Moon increases.
Answer:
I think No since the gravitational force of earth is not eneogh to pull moon to it
