Final answer:
The force of gravity on a 75kg person on skis is calculated using the formula F = mg, resulting in 735.75 N, which rounds to 735 N, making option 1 the correct answer.
Step-by-step explanation:
The force of gravity acting on a 75kg person on skis going down a hill sloped at 30.0 degrees can be found using the formula F = mg, where m is the mass and g is the acceleration due to Earth's gravity (9.81 m/s²).
Calculating this, we have F = (75.0 kg) × (9.81 m/s²) = 735.75 N. Therefore, the closest answer to the force of gravity acting on the person is 735 N, which makes answer 1 the correct option.
