4a4aF-9.Which of the following graphs is correct for kinetic energy (E) and potential energy (U) (with height (h)d (h << Remeasured from the ground) for a particle thrown vertically upward from a horizontal grounand U = 0 at h 0)(B) g(C) 2(D)|HeightHeightHeightHeightThe forca acting on a body moving along x-axis varies with the position of the particle as shown in the

Answer»

Kinetic energy decreases as the ball goes up as the ball is facing negative acceleration so its speed reduces and hence the kinetic energy. The potential energy increases as the height increases.Therefore option A
