Question
The roller coaster car has a mass of 900 kg, including its passenger. It starts from the top of the hill \( A \) with a speed \( v_A = 4.1 \, \text{m/s} \). Neglect friction, the mass of the wheels, and the size of the car. Take \( \rho_B = 7.5 \, \text{m} \) and \( \rho_C = 5 \, \text{m} \). ([Figure 1](#)) ### Figure The figure illustrates a roller coaster track with three major points of interest labeled \( A \), \( B \), and \( C \). - Point \( A \) is at the top of a hill with an initial height \( h \). - Point \( B \) represents a loop with a radius of 15 meters. - Point \( C \) represents a smaller loop with a radius of 10 meters. ### Part A **Problem:** Determine the minimum height \( h \) of the hill crest so that the car travels around the inside loops without leaving the track. **Instructions:** Express your answer to three significant figures and include the appropriate units. **Input Field:** \( h = \) [Input box for value with units] ### Part B **Problem:** What is the normal reaction on the car when the car is at \( B \)? **Instructions:** Express your answer to three significant figures and include the appropriate units. **Input Field:** \( N_B = \) [Input box for value with units]
