Two particles of different mass start from rest. The same net force acts on both of them as they move over equal distances. How do the magnitudes of their final momenta compare?
The particles have equal momenta.
b. The particle of smaller mass has more momentum.
c. The particle of larger mass has more momentum.
d. Either particle might have more momentum.
The Attempt at a Solution
Ok I started by working out the kinetic energy for both particles would be equal.. Force x Distance.
Now from this It would make sense to me that the lighter particle would have a higher velocity over distance, due to V^2 in 1/2MV^2. So if we look at momentum, MV, it would be greater for the smaller mass? Noting the mass is less, but the Velocity has been squared.
Answer is C
