Which of the scenarios below has the most amount of kinetic ene A. A3 kg object

Question

Which of the scenarios below has the most amount of kinetic ene A. A3 kg object moves at an instant velocity of 5 m/s in the +y direction with an acceleration of 6m/s2, in the -y direction B. A2 kg object moves with an instant velocity of 6 m/s and is also bein pushed by a force of 100 N, both in the +a direction C. A 3 kg object moves with an instant velocity of 4 m/s with an acceleration of 1 m/s both in the -y direction Pick the correct answer Scenario A Scenario C All scenarios have the same amount of kinetic energy Scenario B

Explanation / Answer

A. KE = m v^2 / 2 = 3 x 5^2 /2 = 37.5 J

B. Ke = 2 x 6^2 /2 = 36 J

C. KE = 3 x 4^2 /2 = 24 J

Mzximum KE = Scenior A

Ans: Scenerio A
