Question

Give reasons: 1.Road accidents at high speed are very much worse than road accidents at low speed 2.A car driver prefers to hit something soft say stock than a wall if his car goes out of control 3.Shockers are provided in vehicles 4.Chinaware is packed with soft materials during transportation 4.Car passengers are advised to wear seat belts

Answer 1

1. As momentum= mv, so higher speed will cause higher momentum and cause of this higher momentum more force will be applied on it when it gets hit

2. I don't know about this

3. Shockers are provided to absorb or reduce the shocks or bumps while driving and thus making the drive smoother

4. The soft material absorbs any bumps and do not cause scratches on the china ware

5. With out the seat belts, when all of a sudden brakes are applied large force is felt by the driver, as the car comes to rest in no time. But with belts a gradual decrease in velocity is felt and thus keeps the driver safe from accidents

Answer 2

road accidents at high speed in world much larger changes in the momentum in a much smaller time. therefore the forces develop a very huge resulting in a disaster.
