U=8m/s
a=1m/s2
s=18m
v=?
we know
v2=u2+2as
v2=82+2*1*18
v2=100
v=10m/s
it is travelling at a speed of 10m/s
A car is travelling along the road at 8m/s.IT accelerates at 1m/s for a distance of 18m.how fast is it then travelling?

U=0
A=2m/S2
T=10s
V=u+at
V=0+2×10
U=20m/s
S=ut+1/2 at2
=0×10+1/2×10×10=100m
A=2m/S2
T=10s
V=u+at
V=0+2×10
U=20m/s
S=ut+1/2 at2
=0×10+1/2×10×10=100m
