Answer:
O 47 kg. m/s if they were initially headed opposite direction
O 145 kg. m/s if they were initially headed the same direction
The other two are possibilities as well if velocities are initially at an angle
Explanation:
Since the total distance for all three of the planets is 196.2 million miles, you would add planet i and planet iii, then subtract that number from 196.2
planet i and planet iii equaled 54.9 million miles, that subtracted from 196.2 equals 141.3
So your answer is 141.3 million miles
P=w/t
w=15
t=3
therefore, 5 watts (b)
