Final answer:
The potential energy of the roller coaster car at point A, with a mass of 350 kg and at a height of 95 meters, is calculated using the formula PE = mgh. This results in a potential energy of about 323,300 Joules, which is not listed in the provided options.
Step-by-step explanation:
To calculate the potential energy (PE) of the roller coaster car at point A, we use the formula for gravitational potential energy, which is PE = mgh, where m is the mass in kilograms, g is the acceleration due to gravity (9.8 m/s2 on Earth), and h is the height in meters above the reference point. Given that the distance from the ground to point A is 95 meters and the combined mass of the car and people in it is 350 kg, we can calculate the potential energy as follows:
PE = mgh = 350 kg × 9.8 m/s2 × 95 m = 323,300 Joules or 323.3 kJ
Therefore, the correct option that matches our calculation is not listed among the options A through D. The exact value should be approximately 323,300 Joules.
