Answer:
Total no. of missions in a year = 3 (approx)
Given:
Total Energy received by the Earth from the sun per day =
Percent Energy used to accelerate spaceship = 0.75%
Solution:
Now, to calculate the number of launches possible in a year, we first calculate the number of days this energy would last and it is given by:
Number of days for the energy to last, n =
Number of days for the energy to last, n = = 133.34 days
Total no. of missions in a year =
Total no. of missions in a year = = 2.7
Total no. of missions in a year = 3 (approx)
