Question

Jason is traveling down Turkey Street at 22.8 m/s in his 1520 kg 1992 Camaro. He spots another police car and slows down to a legal speed of 20.1 m/s. What is the kinetic energy of the Camaro after slowing down?

a) 1.0 kE
b) 10.0 kE
c) 100.0 kE
d) 40.0 kE

Answer 1

The kinetic energy of the Camaro after slowing down is approximately 308,132.4 J.

Step-by-step explanation:

Kinetic energy (KE) is given by the equation KE = 1/2 mv^2, where m is the mass of the object and v is its velocity. In this case, the mass of the Camaro is 1520 kg and its initial velocity is 22.8 m/s. After slowing down to 20.1 m/s, we can calculate the new kinetic energy. Plugging in the values, we get KE = 1/2 * 1520 * (20.1)^2 = 308,132.4 J. Therefore, the kinetic energy of the Camaro after slowing down is approximately 308,132.4 J.
