Question

A 1000-kilogram space vehicle travels at 5 meters per second along the level road. The magnitude of the normal force acting on the vehicle is approximately A) 1000N B) 5000N C) 10000N D) 50000N

Answer 1

C = 10000N

Step-by-step explanation:

On a level surface, with no other force acting on the vehicle,

|Normal force| = |Weight|,

Weight = mass * acceleration due to gravity

= 1000 kg * 9.8 m/s^2 or N/kg

= 9800 N

--> 10000 N rounded to one significant digit
