(a) State the relation between distance and time : (1) when a body is moving with uniform velocity. (2) when a body is moving with variable velocity. (b) How is distance different from displacement? (c) A train is travelling at a speed of 90 km/h . Brakes are applied in the train so as to produce a uniform accacceleration of 0.5 m/s^2 . Find distance for the train, before it is brought to rest?​

Answer 1

Answer:

your questions are of 9th std so I will tell you

Explanation:

so see your answer :-speed is 90 km/h so now 90 divided by 0.5 so means it will come.................................180 so now remains 2 so 90 ➗ by 2 = 45 now final 180 ➗ by 45 answer will come 4
