Need serious help. Please answer with labels so i know where to put certain answers!!!

ID: A Name: Free Response - Work MUST be shown to receive credit for each part of the response, 16. (10 pts) A 1.60-kg mass is taken to the top of a track at 2.33 m (h/) above the lowest point. See Figure 3 below. - Point A Point C Figure 3 Point B Rough Portion of Track hz A) (2 pts) Calculate the Gravitational Potential Energy of the mass at Point A (see Figure 3 above) with respect to the bottom (the lowest point on the track). B) (4 pts) The mass is released from rest from Point A at the top of the track. Calculate the speed of the box when it gets to the bottom at Point B (see Figure 3 above). Assume there are no heat, sound, friction, or dissipated energy from Points A to B. C) (4 pts) The mass then moves over a portion of the track that is rough and has friction (see Figure 3 above). While moving across this rough surface, there is 12.5 J of energy lost. How high (h2) will the mass go before stopping at Point C
