0.5m/s. Take the velocity of the bug and subtract from the velocity of the oncoming breeze because they are opposite. If the breeze was in the same direction that the bug was flying, then your answer would be the sum of the two.
7.5 I think because it can not be 9 because it’s not close to 50
Answer:
The fraction of kinetic energy lost in the collision in term of the initial energy is 0.49.
Explanation:
As the final and initial velocities are known it is possible then the kinetic energy is possible to calculate for each instant.
By definition, the kinetic energy is:
k = 0.5*mV^2
Expressing the initial and final kinetic energy for cars A and B:


Since the masses are equals:

For the known velocities, the kinetics energies result:




The lost energy in the collision is the difference between the initial and final kinectic energies:


Finally the relation between the lost and the initial kinetic energy:


That is 164.592cm = 5.4 feet
