Answer:
Explanation:
Given
mass of astronaut m=80 kg
Drift d=5 m
Power P=1000 W
time allowed for laser t=1 hr
Force Provided by laser 
, where c=velocity of light
acceleration 
Using Kinematic relation

here initial velocity is zero




distance traveled




Distance left to travel is d=5-0.27=4.73 m
Oxygen left for 9 hrs
time to cover 4.73 m



Therefore he will be able to cover 5 m before emptying cylinder
The answer would be the letter b
