Let's see.

Explanation:

Kinetic Energy #E=1/2mv^2#.

For getting Kinetic energy in S.I. unit, convert all C.G.S. units into S.I.

For eg. Given, #200g=200/1000kg=0.2kg#.

(1). #E_(app)=1/2(0.2).(12)^2# Joules.

#:.E_(app)=14.4J#. (Answer).

(2). #E_(boy)=1/2(60).(3)^2# Joules.

#:.E_(boy)=270J#. (Answer).

Hope it helps :)
