To calculate the power required to reduce the velocity of the vehicle, we need to follow these steps:1. Calculate the change in kinetic energy of the vehicle.2. Calculate the work done to change the kinetic energy.3. Calculate the power required to do the work.Step 1: Calculate the change in kinetic energy.The kinetic energy of an object is given by the formula: where is the mass of the object and is its velocity.Given:Mass of the vehicle, Initial velocity, Final velocity, Calculate the initial and final kinetic energies: Calculate the change in kinetic energy: Step 2: Calculate the work done to change the kinetic energy.The work done is equal to the change in kinetic energy: Step 3: Calculate the power required to do the work.Power is defined as the rate of doing work: where is the time taken.Given:Time, Calculate the power: Therefore, the power required to reduce the velocity of the vehicle from 19.5 m/s to 3.20 m/s in 11.0 s is approximately 26890.73 W.
