in a head-on collision between a large dump truck and a subcompact car, you are better off being in the truck. the car is crushed but the truck is only dented. why? newton's third law tells us that both vehicles experience equal forces. strangely, the drivers do not. suppose a large truck and a small car are moving towards each other at a speed of 6.92 m/s. they collide and stick together after they crash. each driver has mass 82.6 kg. the total vehicle masses are 810 kg for the car and 4280 kg for the truck. note that these values include the masses of the drivers. if the collision time is 0.129 s, (a) what force does the seat belt exert on the truck driver? (b) what force does the seat belt exert on the car driver? give the magnitude of the forces.
