A 60 kg man is standing at the Earth's surface. (a) What is the approximate magnitude of the gravitational force on the man by the Earth. Give your answer in newtons. Get the mass and radius of the Earth from the inside back cover of your text. Remember, enter only the number; don't try to enter the units.

A man with a mass of 110 kg decides to lose weight by climbing the stairs in his office building several times a day. With his current daily activities and food intake, his weight is stable, but he would like to lose 0.5 kg per week without reducing food intake. Data shows that a person must burn 8000 Cal to lose 1 kg of mass (1 Cal = 4.19 x 103 J). If each story of the office building has...
A 1.88 -m ( 6 ft 2 in. ) man has a mass of 81 kg,...
A 1.88 -m ( 6 ft 2 in. ) man has a mass of 81 kg, a body surface area of 1.8 m 2 , and a skin temperature of 35.7 ∘ C. Normally, 80 % of the food calories he consumes go to heat; the rest goes to mechanical energy. His emissivity e is 1 because his body radiates almost entirely nonvisible infrared energy, which is not affected by skin pigment. (Careful! His body at 35.7 ∘ C radiates...

on 15 of 17 > A 1.88-m (6 ft 2 in.) man has a mass of 95 kg, a body surface area of 2.1 m², and a skin temperature of 34.5 °C. Normally, 80% of the food calories he consumes go to heat; the rest goes to mechanical energy. His emissivity e is 1 because his body radiates almost entirely nonvisible infrared energy, which is not affected by skin pigment. (Careful! His body at 34.5 °C radiates into the environment...

What is the weight (in N) of a 1.75 kg mass at the Earth's surface? (Note:...
What is the weight (in N) of a 1.75 kg mass at the Earth's surface? (Note: Acceleration due to gravity is 10 m/s2). Please report your answer to three significant figures and use the abbreviated form of the unit in your answer.
How far above the surface of the Earth will a person’s weight be reduced to one-quarter...
How far above the surface of the Earth will a person’s weight be reduced to one-quarter its value at the surface? g=Gme/r2 where me is the mass of the Earth, r is the distance from the Earth’s center to the height above Earth and G is the proportionality constant. You will need to look up the mass and radius of the Earth.
