Answer:
200J
Explanation:
Given,
Mass(m) = 10g
= 10 × 0.001kg
= 0.01kg
= 10^-2 kg
Velocity(v) = 200 m/s
To Find :-
Kinetic Energy(K.E).
Formula Required :-
Solution :-
= 200J
K.E = 200J
Know More :-
1) K.E = 1/2 mv^2
- m = mass
- v = velocity
- K.E = Kinetic Energy
2) P.E = mgh
- m = mass
- g = gravity
- h = height
- P.E = potential energy
