The correct answer to the question is : 4,400 N.
Step-by-step explanation:
The mass of the space vehicle m = 1200 Kg.
The speed of the space vehicle v = 4.8 m/s.
The gravitational field strength E = 3.7 N/Kg.
We are asked to calculate the normal force on the space vehicle.
The gravitational force that acts on the space vehicle is calculated as -
Force F = E × m
= 3.7 N/ Kg × 1200 Kg.
= 4.440 N.
The normal reaction on the space craft is equal to the force of gravity on Mars.
Hence, the normal reaction on the space vehicle is 4,440 N.
