Question

please solve the question with explination.​

Answer 1

Answer:

1. a=v-u/t

at=v-u

u+at=v

hence, proved that u+at=v and not v=u+at^2

2. P.E.= mgh

g is acceleration due to gravity

acc=v/t

acc=s/t^2

h= distance

hence, m×d×d/t^2

hence, it's answer is m^1L^2t^-2

mass=1

length=2

time=-2
