Bro it's an easy formula…for finding K.E.(Kinetic energy). -
The formula is 1/2 m v^2
So mass is 2 kg
Velocity is 3 m/s
Max. K.E. = 1/2 ×2 × 3 =3 kg m /sec..
Hopping it was easy to understand

Answer: 9J
Explanation:
mass :- 2kg
v :- 3m\s
v^2 =u^2+2gS
3^2=0^2+2*9.8*S
9 = 19.6S
S = 9\19.6
S = 45\98
GPE = 2×9.8×4.5\9.8
GPE = 9J
