4. A roller-coaster car with a mass of mr= 200 kg 200.0kg (including the riders) is moving 4.00 m A to the right at a speed of 4.00m/s at point A in the diagram. This point is 15.0 m B 15.0m above the ground. Determine the 6.0 m speed at point B if all forms of resistive forces are ignored. If the speed of the roller-coaster at point B is actually approximately 12.6m/s, what is the work done by all resistive forces? Answer: Without resistive forces, the speed of the roller-coaster at Point B will be approximately 13.3m/s. Given the actual speed, the work done by all the resistive forces will be 3.40×10' J.
