Question

question 12 of 25 a 50 kg aardvark runs with a speed of 6 m/s. what is the kinetic energy of the aardvark? a. 150 j b. 300 j c. 600 j d. 900 j

Explanation:

Step1: Recall kinetic energy formula

$KE = \frac{1}{2}mv^2$

Step2: Substitute values (m=50kg, v=6m/s)

$KE = \frac{1}{2} \times 50 \times 6^2$

Step3: Calculate velocity squared

$6^2 = 36$

Step4: Compute result

$KE = 0.5 \times 50 \times 36 = 900\ \text{J}$

Answer:

D. 900 J
