by conservation of energy,
the energy spent in doing the work=change in ke + change in pe
therefore, 230=10 x 2 x 2 + 0.5 x 10 x v2
230=40+5v2
v2=190/5
=38m/s
now,v2=2as
a=38/4
=9.5 m /s2

According to mechanical energy conservation :- 230 = 1/2*10*v^2 + 10 * 10 * 2230-200= 5v^2v^2 = 2as6/2*2=a= 1.5m/s^2
