At some point during construction, the International Space Station had a mass of 235,565 kg. When it orbited the Earth at an altitude of 400,000 m,
what was the approximate gravitational force on the Station due to Earth's
gravity? (Recall that Earth has a radius of 6.37 * 106 m, it has a mass of 5.97
x 1024 kg, and G = 6.67 * 10-11 N·m²/kg?.)
A. 3.6 x 106 N
B. 3.1 x 106 N.
mm
C. 2.0 x 106N
D. 3.9 ~ 106 N

Boxing gloves are padded to lessen the force of a blow. (a) calculate the force exerted by a boxing glove on an opponent’s face, if the glove and face compress 7.50 cm during a blow in which the 7.00-kg arm and glove are brought to rest from an initial speed of 10.0 m/s. (b) calculate the force exerted by an identical blow in the gory old days when no gloves were used and the knuckles and face would compress only 2.00 cm. (c) discuss the magnitude of the force with glove on. does it seem high enough to cause damage even though it is lower than the force with no glove?
