I need help with this conceptual question. Please provide astep-by-step solution to this question. Thank You!
Jogger A has a mass m and a speed v, joggerB has a mass m/2 and a speed 3v, jogger C has amass 3m and a speed v/2, and jogger D has a mass4m and a speed v/2. Rank the joggers in order of decreasingkinetic energy. Indicate ties where appropriate. Rank from highest to smallest. Torank items as equivalent, overlap them. Please list answer fromhighest energy to smallest energy. I need help with this conceptual question. Please provide astep-by-step solution to this question. Thank You!

Explanation / Answer

Ka = mv2/2 Kb = (m/2)(3v)2/2 = 9mv2/4 Kc = (3m)(v/2)2/2 = 3mv2/8 Kd = (4m)(v/2)2/2 = mv2/2 answer: Kb > Ka = Kd >Kc
