Question

A body is falling downwords 48 meter in 4 seconds .Calculate , what distance would it fall in 9 seconds . Given that, when a body falls , distance various directly as the square of time.​

Answer 1

Step-by-step explanation:

Let d be the distance from starting point and t be the time, then according to question

d=kt

2

Given d=402.5 for t=5. So,

402.5=k.5

2

k=

25

402.5

=16.1

So,

d=(16.1)t

2

For t=10

d=(16.1)100=1610 feets

and distance for t=9

d=(16.1)81=1304.1 feets

Distance fallen in 10th second =distance at t=10 - distance at t=9

=1610−1304.1=305.9 feets
