thekineticergy of the bertically up with initilal velocity. Which of the following graphs representsenergy of the ball?K.EĐ.ĐK.EK.E |
|
Answer» since the expression of kinetic energy is 1/2*m*v² so the graph will be like parabolic. as v² is changing as the ball goes up and fall down. since the initial velocity will decrease as it goes up and stops then the velocity will become 0. again when fall down starts it will follow same curve but the curve will be increasing. ao the correct answer is A. |
