Homework Answers
accelerates with 1 g for 60 seconds
a = 9.8 m/s2
t = 60 sec
s = vot + 1/2at2
s = 0 + (0.5*9.8*602)
d1 = s = 17640 m
v = v0 + at
v = 0 + (9.8*60)
v = 588 m/s
constant speed for another 60 seconds
d2 = v*t
d2 = 588*60
d2 = 35280 m
total trip = 17640 + 35280 = 52920 m
total trip = 52.92 km
