A weight, with an unknown mass, falls through a distance of 10 millimeters (mm) onto a collar attached to the bottom end of a vertical bar. The bar is 3 meters (m) long and has a cross-sectional area of 600 square millimeters (mm2). The impact causes the bar to instantly stretch by 2 mm. The Young's modulus of the bar material is 200,000 MPa. Determine: 1. The weight of the falling object. 2. The stress experienced by the bar due to the impact.
