While visiting the amusement park, Sarah and Sam choose to ride the bumper cars while their instructor records video of their collisions. Back in the classroom, the students analyze a head-on collision between Sarah and Sam’s two cars. The velocity of each car after the collision is equal to the velocity of the other car before the collision (i. e., the cars switch velocities). What can the students infer about the masses of the bumper cars?

Their masses are equal because both momentum and kinetic energy are conserved.
Their masses are unequal because both momentum and kinetic energy are conserved.
Their masses are unequal because neither momentum nor kinetic energy is conserved.
Their masses are unequal because neither momentum nor kinetic energy is conserved.

Aspring with an unstrained length of 0.071 m and a spring constant of 2.6 n/m hangs vertically downward from the ceiling. a uniform electric field directed vertically upward fills the region containing the spring. a sphere with a mass of 5.29 10-3 kg and a net charge of +7.2 µc is attached to the lower end of the spring. the spring is released slowly, until it reaches equilibrium. the equilibrium length of the spring is 0.058 m. what is the magnitude of the external electric field?
