d) It is impossible to tell from the information given. a) TH 7.8 Which of the following statements about car collisions is (are) true? b) T a) The essential safety benefit of crumple zones (parts of the front C) TH of a car designed to receive maximum deformation during a head on collision) is due to their absorbing kinetic energy, converting it d) T into deformation, and lengthening the effective collision time, thus e ) reducing the average force experienced by the driver. 7.12 b) If car 1 has mass m and speed v, and car 2 has mass 0.5m and speed the fo 1.5v, then both cars have the same momentum. a Th C) If two identical cars with identical speeds collide head on, the b Th magnitude of the impulse received by each car and each driver is the same as if one car at the same speed had collided head on with a c) Th concrete wall. d) Th d) Car 1 has mass m, and car 2 has mass 2m. In a head-on collision of e) Th these cars while moving at identical speeds in opposite directions, car 7.13 experiences a bigger acceleration than car 2. shot f e) Car 1 has mass m, and car 2 has mass 2m. In a head-on collision of block these cars while moving at identical speeds in opposite directions, car 1 mass I receives an impulse of bigger magnitude than that received by car 2. bullet 7.9 A fireworks projectile is launched upward at an angle above a a) 397 large flat plane. When the projectile reaches the ton
