Question

les A body moving with uniform acceleration travels 90 m in 8 s and 200 m in the next 7
(i) Find the initial velocity of the body.
(ii) Find the acceleration of the body.​

Answer 1

here S=90m,t=8s,here u= 90/8=11(approx)

next S=200m,t=8+7=15s,so here v=200/15=13(approx)

v=u+at

13=11+15a

15a=13-11

15a=2

a=2/15m/s²

a=0.13m/s²

1) initial velocity=11m/s

2) acceleration=0.13m/s²
