Asatellite with a mass of 2,000 ㎏ is inserted into an orbit that is twice the earth' s radius. w hat is the force of gravity on the satellite? the radius of the earth is 6380 km, and the mass of the earth is 5.98 x 1024 kg a. 2,000 n h. 4,900 n 19,600 n d 24,500 n e 36.200 n l space station which orbits earth, astronauts experience apparenst

option (b) 4900 N

Explanation:

m = 2000 kg, R = 6380 km = 6380 x 10^3 m, Me = 5.98 x 10^24 kg, h = R

F = G Me x m / (R + h)^2

F = G Me x m / 2R^2

F = 6.67 x 10^-11 x 5.98 x 10^24 x 2000 / (2 x 6380 x 10^3)^2

F = 4900 N

the design of a ski jumping suit involves a trade-off between giving the skiers lift to get higher jumps and ensuring the skier does not face a lot of drag before the jump itself. an expansive suit may to lift the skier higher, but at the same time, it will also increase the air resistance. higher air resistance as the skier goes down the slope limits the speed of the jump. a big suit also increases the risk of losing balance or control, especially if there's a strong gust of wind. while technologically enhanced suits a lot, clothing is not the only factor in a ski jumper’s success. gathering speed while skiing down the slope, ensuring good speed on the ramp, and maintaining good body posture and form in the air all contribute to a ski jumper's success.

the answer is 100. i just did this lesson and got a 100% on it. : )
