Final answer:
The normal force applied to the bobsled on a slope at a 73-degree angle with a mass of 1100 kg, assuming no friction, is calculated using the formula N = m × g × cos(θ), which yields a value closest to option (C) 3300 N.
Step-by-step explanation:
The question is about finding the normal force being applied to a bobsled on a slope. The mass of the bobsled is given as 1100 kg, and the angle of the slope is 73 degrees. Assuming there is no friction, the normal force is the component of the sled's weight that acts perpendicular to the surface of the incline. The gravitational force acting on the sled is the product of its mass and the acceleration due to gravity (g = 9.8 m/s2). The normal force can be calculated using the formula N = m × g × cos(θ), where m is the mass, g is the acceleration due to gravity, and θ is the angle of the incline.
Plugging in the given values, N = 1100 kg × 9.8 m/s2 × cos(73°). The cosine of 73 degrees is approximately 0.292, so:
N = 1100 × 9.8 × 0.292 ≈ 3141.84 N
The closest option to this calculated value is (C) 3300 N, which indicates a slight rounding difference in the actual calculation.
