The mass of a ball A is double the mass of another ball B. The ball a moves at half the speed of the ball. B. Calculate the ratio of the kinetic energy of A to the kinetic energy of B, |
|
Answer» Correct Answer - A::B mass of ball `A = 2m`, mass of ball `B = 2 upsilon` velocity of ball `A = upsilon," velocity of ball" B =2upsilon` `("Kinetic energy of ball A")/("Kinetic energy of ball B") = ((1)/(2)(2m)upsilon^2)/((1)/(2)m(2upsilon)^2) =("mv"^(2))/(2"mu"v^2) = (1)/(2) = 1:2` |
