Answer:
Initial velocity is zero.
Step-by-step explanation:
According to second equation of motion
[tex]s=ut+\frac{1}{2} at^2[/tex]
where s = distance traveled
t = time taken
a = acceleration
u = initial velocity
here in the question we have
s = 10 m
t = 1 second
a = 20[tex]ms^{-2}[/tex]
plugging the known value in order to find the unknown which is u (initial velocity)
[tex]10=u(1)+\frac{1}{2} (20)(1)^2[/tex
10 = u +10
gives u =0
therefore initial velocity is zero.
