Question

Could anyone pls solve all the numericals
there is no hurry I want within 3 days
those who solved I will mark as brainliest answer ​

Answer 1

15-

as per the equation of motion v=u+at

u=5m/s

v=find

t=5s,a=2m/s²

v=5+2(5)=15m/s

16-

1) 5m/s

18×1000m/3600s=5m/s

2)retardation

v=0

u=5m/s

a=find

t=5s

0=5+a(5)

a=-1m/s²

3)u=5m/s

   v=find

   a=-1m/s²

    t=2s

 v=5-1(2)=3m/s
