Question

The distance through which a freely falling body drops is directly proportinal to the square of the time for which it drops. If a body falls through 640 m in 8 second, then find the distance that the body falls through in the next 2 second.​

Answer 1

Answer:

Step-by-step explanation:

Given is distance is proportional to the square of the time.

D∝T²

D=kT²  ---------------('K' is the proportionality constant)

640 = k8²

k=10

Distance traveled in next 2 seconds-:

D=10×2²

D=400m

Therefor the body will travel a distance of 400 metres in next 2 seconds
