Unformatted text preview: At the very instant that it stops, before it has had time to slow down appreciably, what is the drag force on each swimmer? What is the propulsive force? c) How long will each swimmer “coast”: i.e. how long will it keep moving forward before stopping? d) How far did it travel during the “coast”ing phase? 2. An elephant and a mouse fall from a 15 foot height. Explain (using as quantitative terms as possible) why the elephant will likely be injured, but the mouse will not. 3. The elastic modulus for three different materials is given below: a) Bone 15,000 MPa b) Brain tissue 0.005 MPa c) Artery 3 MPa Draw stress versus strain diagrams for each of these materials....
