Object K with a mass of 1 kg is dropped from a height of 3 m as in the figure. If the ground is smooth and the coefficient of return between the ground and the object A is 0.6 a) Define the (local) coordinate system with respect to the axis of impact. b) According to these coordinates, find the speed of hitting the ground as vector. c) Calculate the rebound velocity from the H point as vector based on the coefficient of return. (Velocity after impact) d) Calculate the impulse due to the surface response. (You do not need to calculate the surface response.)
