Answer:
the final speed of object A changed by a factor of = 0.58
the final speed of object B changed by a factor of = 1.29
Explanation:
Given;
kinetic energy of object A, = 27 J
let the mass of object A =
then, the mass of object B =
work done on object A = -18 J
work done on object B = -18 J
let be the initial speed
let be the final speed
For object A;
Thus, the final speed of object A changed by a factor of = 0.58
To obtain the change in the final speed of object B, apply the following equations.
Thus, the final speed of object B changed by a factor of = 1.29
