If justin has a mass of 50kg on earth what is his weight on earth and on the moon?

The separation distance between two 1.0 kg masses is changed. How is the mutual gravitational force affected in each case? (Assume F2 represents the new force and F1 represents the original force.) (a) The separation distance is three-fourths the original distance.F2 / F1 = (b) The separation distance is 7 times the original distance.F2 / F1 =

An astronaut on the moon places a package on a scale and finds its weight to be 35 N. (a) What would the weight of the package be on the earth?                      N(b) What is the mass of the package on the moon?                      kg(c) What is the package's mass on earth?                       kg

2) What is the weight of a 68-kg astronaut (a) on Earth (b) on the Moon (g=1.7 m/s^2) (c) on mars (g=3.7 m/s^2) (d) in outer space traveling with constant velocity?

On the moon, the acceleration due to gravity is equal to 1.67 m/s^2.  How much does an astronaut weigh there, whose mass combined with his spacesuit is 171 kilograms.?  Express your answer in units of Newtons.

A planet was discovered which is twice as massive as Earth and has twice Earth's radius. How does the value of the gravitational field strength on the surface of that planet compare to the value of the gravitational field strength on the surface of Earth (gEarth)?   1/2gEarth 1/8gEarth gEarth 1/4gEarth 2gEarth 4 g Earth

A "doomsday" asteroid with a mass of 1.0 × 1010 kg is hurtling through space. Unless the asteroid's speed is changed by about 0.25 cm/s, it will collide with Earth and cause tremendous damage. Researchers suggest that a small "space tug" sent to the asteroid's surface could exert a gentle constant force of 2.4 N . For how long must this force act?

The weight of an astronaut plus his space suit on the Moon is only 292 N. How much (in N) do they weigh on Earth? (The acceleration due to gravity on the Moon is 1.67 m/s2.)

Your sister weighs 430 N on Earth (g = 9.80 m/s2). If you take her to Mars (g = 3.75 m/s2), find her mass on Mars.
