The weight of an astronaut plus his space suit on the moon is only 291 n. how much (in n) do they weigh on earth? (the accelerat
Oksanka [162]
Weight on the Moon = 291 N.
W = g · m, where m stays for the mass and on the Moon g = 1.67 m/s²
291 N = 1.67 m/s² · m
m = 291 kg m / s² : 1.67 m/s²
m = 174.25 kg
Weight on Earth = 9.81 m/s² · 174.25 kg = 1,709.4 N
Answer:
The weight of an astronaut on Earth is 1,709.4 N.

Shalnov [3]

Answer:

94.74 km/hr

26.3 meters/sec

Explanation:

150 km/(95/60) hr = 9000/95 kph  = 94.74 km/hr

(150 km * 1000m/km)/(95 min * 60 sec/min) = 150000/5700 m/sec  

= 26.3 meters/sec

Hopefully, this is right!
