A package 7kg mass is sliding down the parabolic chute Y = X2/18 where X and Y are measured in m. At point A the velocity of the box is 2.5 m/s and acceleration is 1.5m/s2, as shown in Figure Q3 (not to scale). Find: a) The Normal force between the package and the chute at point A. b) The Friction force between the package and the chute at point A. OOOOOO Y (m) Y = X2/18 A 2m X (m) Figure Q3
