Task 4: The Moon has a mass of 7.4*10^22 kg and the Earth has a mass of 6.0*10^24 kg. The average distance
between the Earth and the Moon is 3.8*10^8 m. If you travel directly between the Earth and the
Moon in a rocket, calculate the gravitational potential when you are 1.0*10^7 m from the Moon.

i had this question and the answer was 3.15 miles.

martina travels from school to her mom's office. from there, she walks to school. after school, she walks to the library and then to a friends house before finally ending back at home. find martina's total distance traveled.

a) 0 miles  

b) 0.4 miles  

c) 1 mile  

d) 3.15 miles

0.93xc=0.93x3x10^8m/s

2.54cm is 1 inch

360seconds i 1 hr

distance = 150m

displ = root (50 ^2 + 100^2)

root(2500+10000)

root 125000
