Question

Your 1500 kg car is behind a truck traveling at 60 mph (27 m/s). to pass the truck, you speed up to 75 mph (34 m/s) in 6.0 s. we seek the engine power is required to do this. first calculate: how much kinetic energy does the car have at first (27 m/s)? (input your answer in joules.)

Answer 1

The car has a kinetic energy of 364,500 joules at a velocity of 27 m/s.

Step-by-step explanation:

To calculate the kinetic energy of the car at a velocity of 27 m/s, we can use the formula:

Kinetic Energy (K.E.) = 0.5 * mass * velocity^2

Given that the mass of the car is 1500 kg and the velocity is 27 m/s, we can substitute these values into the formula:

K.E. = 0.5 * 1500 kg * (27 m/s)^2

Simplifying the equation, we get:

K.E. = 364,500 joules

Therefore, the car has a kinetic energy of 364,500 joules at a velocity of 27 m/s.
