You are at the top of the empire state building on the 102nd floor, which is located 373 m above the ground, when your favorite superhero flies over the building parallel to the ground at 70.0% the speed of light.
you have never seen your favorite superhero in real life. out of curiosity you calculate her height to be 1.50 m . if the superhero landed next to you, how tall would she be when standing?
a). 2.10 m
b). 1.50 m
c).1.15 m
d). 1.07 m

Write the equation for momentum, first using symbols for the variables, then using words for the variables.

1point) a skydiver weighing 130 lb (including equipment) falls vertically downward from an altitude of 14,000 ft and opens the parachute after 20 s of free fall. assume that the force of air resistance, which is directed opposite to the velocity, is of magnitude 0.85|v|0.85|v| when the parachute is closed and is of magnitude 17|v|17|v| when the parachute is open, where the velocity vv is measured in ft/s. assume that acceleration due to gravity has magnitude 32 ft/s/s; remember that weight is the product of mass and gravitational acceleration. find the speed of the skydiver when the parachute opens. speed is 150.6121788 ft/s find the skydiver's height when the parachute opens. height is 2338.98591 ft find the limiting velocity vlvl after the parachute opens. (think about whether this should be positive or negative.) vl=vl= 7.647 ft/s

Two trains leave a station at the same time, train a travels at a constant speed of 16 m/s. train b starts at 8.0 m/s but accelerates constantly at 1.0 m/s squared. after 10.0 seconds, which train has the greater speed?
