The mass and speed of three vehicles is shown below.
(a) Compare the momentum, from most to least.
(b) Compare the kinetic energy, from most to least.
(a)
The ranking form most to least in terms of momentum.
Answer to Problem 1TC
The ranking form most to least in terms of momentum is
Explanation of Solution
Given Info: Mass of the vehicle in the case (A) is
Write the expression for the momentum.
Here,
Substitute
Thus, the momentum of the vehicle in case (A) is
Substitute
Thus, the momentum of the vehicle in case (B) is
Substitute
Thus, the momentum of the vehicle in case (C) is
Conclusion:
Therefore, the ranking form most to least in terms of momentum is
(b)
The ranking from most to least in terms of kinetic energy.
Answer to Problem 1TC
The ranking from most to least in terms of kinetic energy is
Explanation of Solution
Write the expression for the kinetic energy.
Here,
Substitute
Thus, the kinetic energy of the vehicle in the case (A) is
Substitute
Thus, the kinetic energy of the vehicle in the case (B) is
Substitute
Thus, the kinetic energy of the vehicle in the case (C) is
Conclusion:
Therefore, the ranking from most to least in terms of kinetic energy is
