a car is moving at 12 m/s and has a mass of 600 kg. what is the kinetic energy of the car? (formula: $ke=\frac{1}{2}mv^{2}$) 43,200 j 86,400 j 72,600 j 36,300 j

Answer

Explanation:

Step1: Identify values

$m = 600$ kg, $v=12$ m/s

Step2: Apply kinetic - energy formula

$KE=\frac{1}{2}mv^{2}=\frac{1}{2}\times600\times12^{2}$ $=\frac{1}{2}\times600\times144$ $ = 300\times144$ $=43200$ J

Answer:

43,200 J
