only do if u can answer all please the speed of the car and riders total mass 3500 kg at the top

a. We can use the conservation of mechanical energy to find the speed at Point B. The total mech

Question

The speed of the car and riders (total mass = 350.0 kg) at the top of the first hill, Point A, is 4.00 m/s. a. What is the speed at Point B, 5.00 m below Point A. b. The top of the second hill, Point C, is 8.00 m above Point B. Is the roller coaster moving fast enough to make it to the top of the second hill? c. Calculate the minimum speed required at Point B in order for the rollercoaster to reach the top of the second hill, Point C. d. Did you need to know the mass of the car and riders in order to answer this question? Explain. A 1.00 kg pendulum bob is released from a height of 2.00 m. Its speed at the bottom of its swing is 1.95 m/s on the first pass. a. How much energy is lost due to friction on the way to the bottom of the swing of the pendulum? b. How efficient is the pendulum in transferring GPE to KE?
