It's actually my school's physics question.?

Question

A body is movin wid uniform acceleration.It's velocity after 5sec is 20m/s & after 8sec, it's 30m/s.Calculate d distance it will cover in d next 10sec.

Answer 1

u must use equation such as v=u+at,s=ut+1/2 a(t)t ,etc and plz answer my question

Answer 2

find acceleration first.

then use s=ut+1/2at square.

find out dude.

its simple..

Answer 3

Use the equations of motion.

Answer 4

heyy its so easy

in wich stndrd u r?

i think in 9th?

Answer 5

i'm not really sure about the solution, but let's see...

a=(30-20)/(8-5)

  =10/3 m/s-2

can we assume it starts from 0sec. using s=ut+1/2 (a)(t)(t)

distance covered from 0sec to 8sec

s=0(0)+1/2 (10/3)(8)(8)

  =106.67m

distance covered from 0sec to 18sec

s=0(0)+1/2 (10/3)(18)(18)

  =540m

distance from 8sec to 18sec=540-106.67=433.33m

i hope it is correct.
