Question

DATE: PAGE NO. Two identical toy cars of same mass travelling with a speed of 2mls and 2.5 mis respectively respectively which of the two has lesser Kinetic energy. Explain​

Answer 1

Answer:

let the mass of both the cars be m

$kinetic \: energy = \frac{1}{2} m {v}^{2} \\ = \frac{1}{2} m {2}^{2} \: \: \: \: \: \: \: \: \: \: and \: \: \: \: \: = \frac{1}{2} m {2.5}^{2} \\ = \frac{1}{2} m \times 4 \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: and \: \: \: \: \: \: \: = \frac{1}{2} m6.25 \\ = 2m \: \: \: \: \: \: \: \: \: \: \: \: \: \: and \: \: \: \: = 3.175m$

kinetic energy of the second car is morr
