- Analyze the following situation. A student chooses the following energy bar charts to represent the energy for each location. However, one of the charts incorrect. Which one is incorrect? Explain why it is incorrect and propose a better solution. A toy car rolls along a track and up a hill to its highest point (C). Use the given Energy Bar Chart to identify the appropriate Bar Charts for locations A, B, and C. KEY: A: B: C: = Kinetic Consider effects of friction, air resistance, and collisions. B Tap to identify the appropriate Bar Charts for A, B and C = Grav. Potential Dissipated C Elastic Potential Option 3 of 6 Option 2 of 6 Option 5 of 6A. Calculate the work done by the force of gravity when a 7.0 kg object is lifted to a height of 46.0 m above the ground.B. Calculate the velocity with which the object strikes the ground if dropped from that height, using the principle of conservation of energy.C. Calculate the kinetic energy (KE) and the potential energy (PE) of the object at apoint halfway on the path (i.e. at a height of 23.0 m) after it is dropped. To do this, you need to find the object's velocity at that position using an equation of motion. What is the total energy of the object at that point? Does this verify the principle of conservation of energy?A bowler tosses a ball without spin. The ball slides down the alley. At some point, friction with the alley makes the ball start to roll; eventually, it rolls without sliding. When the ball reaches this point, it is moving at a lower speed than the original toss. Use energy concepts to give two reasons for this change.
