If we use the formula for kinetic energy then
K.e = 1/2 mv^2
v= a.t => v= 10m/s^2× 60 s = 600m/s
then we have
K.e. = 1/2 . 1kg . (600m/s)^2
= 1/2 .360000 Kgm^2/s^2 . if u wish to keep minute as unit you have to divide the ans. by (60)^2 i.e. by 3600

Unusual:
see unit of energy will be joule. but just multiply all the units
as energy = F .displacement
send me the solution ... please
thus E = Mass . acc. displacement
what is the value of displacement
that u havent posted
let me see once again
i will edit my answer in few minutes if i find the solution
Ok....send fastly please ....

Answer:
we know, kinetic energy= 1/2mv^2
and, v=at=(10ms^-2)(60s)=600m/s
therefore, kinetic energy=1/2×1×(600)^2
= 1800 J
