A young diver is practicing his skills before an important team competition. Use the diagram below in order to analyze the energies of the diver and complete the statements below.Where m = mass (kg), g = 9.8 m/s2, v = velocity (m/s), h = height (m), KE = kinetic energy (J), and GPE = gravitational potential energy (J).Use the equations above to answer the following questions.A diver with a mass of 90 kg is at a height of 10 m, and he has not jumped off of the board yet (v = 0 m/s). When the diver reaches a height of 5 m (Point C), his gravitational potential energy isA. 1350 JB. 8820 JC. 4410 JD. 0 Jand his velocity isE. 4.5 m/sF. 0 m/sG. 3.2 m/sH. 9.9 m/s Please help will mark brainliest

Question No. 1 Marks = = 5 +5 +2 = 12 The driver of a 2.0 103 kg red car traveling on the highway at 45m/s slams on his brakes to avoid striking a second yellow car in front of him, which had come to rest because of blocking ahead as shown in above Fig. After the brakes are applied, a constant friction force of 7.5 103 N acts on the car. Ignore air resistance.(a) Determine the least distance should the brakes be applied to avoid a collision with the other vehicle? (b) If the distance between the vehicles is initially only 40.0 m, at what speed would the collision occur?(c) Write your conclusive observations on the result obtained from this numerical. i.e. the importance of Physics in daily life.Question No. 2 Marks = 8Consider an automobile moving at v mph that skids d feet after its brakes lock. Calculate how far it would skid if it was moving at 2v and the brakes were locked.
