Question
consider a collision between two carts as seen by observers in two inertial reference frames, moving (at constant velocity) relative to each other. For which of the following quantities will the two observers measure the same values?
The kinetic energy and momentum of each cart.
The total kinetic energy and momentum of the system consisting of the two carts.
The change (due to the collision) in the momentum and kinetic energy of each cart.
The change in the momentum of each cart and in the system's total kinetic energy.
None of the above answers are correct.
The kinetic energy and momentum of each cart.
b.The total kinetic energy and momentum of the system consisting of the two carts.
c.The change (due to the collision) in the momentum and kinetic energy of each cart.
d.The change in the momentum of each cart and in the system's total kinetic energy.
e.None of the above answers are correct.
Explanation / Answer
Given that,
Two carts are moving (at constant velocity) relative to each other.
lf collision is elastic, Change in kinetic energy of each other will be measured by two observers.
As the observers will measure the same relative velocity for each other, change in momentum will be measured
same.
so, the answer is The change (due to the collision) in the momentum and kinetic energy of each cart.
