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
Answer
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
