a 1,500 kg car is driving at a speed of 20 m/s. how much kinetic energy does the car have? remember : $e_k = \\frac{1}{2}mv^2$ $e_k = ?$ j

Answer

Explanation:

Step1: Identify given values

Mass ( m = 1500 , \text{kg} ), velocity ( v = 20 , \text{m/s} ), formula ( E_K=\frac{1}{2}mv^2 )

Step2: Substitute values into formula

( E_K=\frac{1}{2}\times1500\times(20)^2 )

Step3: Calculate ( (20)^2 = 400 )

( E_K=\frac{1}{2}\times1500\times400 )

Step4: Calculate ( \frac{1}{2}\times1500 = 750 )

( E_K = 750\times400 )

Step5: Multiply 750 and 400

( E_K = 300000 )

Answer:

( 300000 )
