Final Answer:
The correct energy transformations occurring when a dragster engine is revved, its clutch let out rapidly, its tires spun, and it starts to accelerate forward . Therefore the final answer is a.
Explanation:
When a dragster engine is revved, it utilizes stored chemical energy from the fuel. This chemical energy is converted into kinetic energy as the engine's components move. When the clutch is released rapidly, this kinetic energy is transferred to the tires, causing them to spin. The spinning tires then transfer the kinetic energy to the dragster, propelling it forward. As the dragster accelerates, it gains potential energy due to its increased height from the ground, considering the ground as a reference point.
First, the chemical energy stored in the fuel undergoes a conversion to kinetic energy within the engine, where the controlled combustion process releases this energy. As the clutch engages and the tires begin to rotate, the kinetic energy transfers from the engine to the tires. This energy transmission enables the tires to grip the surface, initiating motion.
Next, as the dragster moves forward, its kinetic energy transforms into potential energy.This shift occurs as the vehicle gains height from the ground. Despite the dragster’s forward motion, the potential energy increases due to its elevated position relative to the ground. Therefore, the energy transformations within a dragster encompass the conversion of stored chemical energy to kinetic energy, subsequently transitioning to potential energy as the dragster accelerates forward.Thus the final answer is a.
