Hi,
a=v-u/t
==20-4/8
==16/8
==2m/s^2
from above DATA,
v=20
u=4
a=2
t=8
s=?
by using Newton second equation
s=32+64
s=96m
plz mark as brainaist....

v=u+at
》 a=(v-u)/t = (20-4)/8 = 2
Now using 2nd equation of motion:
s=ut+(1/2)×a(t)^2
》 s= 4×8+(1/2)×2×(8)^2
= 32+64
= 96 m
》 a=(v-u)/t = (20-4)/8 = 2
Now using 2nd equation of motion:
s=ut+(1/2)×a(t)^2
》 s= 4×8+(1/2)×2×(8)^2
= 32+64
= 96 m
