Which of the following equations represents the work-kinetic energy theorem? O Work, W = -mv O Work, W = mgh O Work, W = muz + mgh O Work, W = 1mul - 2mus O Work, W = 1mol - 1kxIgnoring friction effects, the amount of energy required to accelerate a car from rest to a speed v is E. The energy is delivered to the car by burning gasoline. How much additional amount of energy is required to accelerate the car to a speed 4v? Hint: Remember that the kinetic energy (E) is proportional to the square of the speed (v-), so if we double the speed (2v) the kinetic energy increases four times (4E). Therefore, the additional amount of energy is 3E (the difference)
