(a) All the cars are provided with seat belts(b) It is dangerous to move out of a moving bus(c) Road accidents at high speeds are very much worse than accidents at lowspeeds

Answer 1

a. When we move we have speed ,so we must have momentum as well as inertia of motion .Hence, in order to prevent this seats belt are their .

b. Moving bus is in motion and moving out from such a motion bus be very dangerous as you will acquire inertia of motion and it will be hard to stop it .

c. High speed gives large momentum, which is their respononsibe for such damage .
