body of mass 10 kg is travelling with uniform speed of 5 m/s. Its kinetic energy is (a) 25 J (b) 125 J (c) 1250 J (d) 1000 J |
Answer» Given:-
To Find:-Solution:-As we know that the energy POSSESS by body due to its motion is called Kinetic Energy. • KE = 1/2mv²Where, KE is the Kinetic Energy m is the mass v is the speed/velocity Substitute the value we get → KE = 1/2×10×5² → KE = 1/2× 10×25 → KE = 250/2 → KE = 125 J Therefore, the kinetic energy of the body is 125 Joules.. Hence, Option (b) 125 J is the correct ANSWER . |
