Question 10 5 pts An insurance company is testing air bag safety. Car A has front air bags and Car B does not. In both cases, the cars are driven into a brick wall with the same momentum. In Car A, the dummy survives, but in Car B, the dummy does not. In terms of impulse and force, please explain this result. The dummy in Car B experienced the same impulse but a greater force than in Car A. The dummy in Car B experienced a greater impulse but the same force as in Car A. Not enough information to determine. The dummy in Car B experienced the same impulse and the same force as in Car A. The dummy in Car B experienced a greater impulse and a greater force than in Car A.

If two triangles are, \( \qquad \) (7.1.1), then the corresponding... . \( (7.1 .2) \) \( \qquad \) (7.1.3) and hence the triangles are similar. (3) 7.2 In the diagram below, diameter EMA of a circle with centre M bisects FAB.MD is a perpendicular bisector to the chord \( \mathrm{AB}, \mathrm{ED} \) is produced to meet the circle at \( \mathrm{C} \). Chord \( \mathrm{CB} \) and \( \mathrm{FE} \) are drawn. 7.2.1 Prove that \( \triangle A F E / / / \triangle A M D \) 7.2.2 Determine the numerical value of \( \frac{A F}{A D} \) 7.2.3 Prove that \( A D^{2}=C D \times D E \) \( [16] \)
