Question

An electron with a speed of 6.00×10^{6} m/sm/s, collides
with an atom. The collision excites the atom from its ground state
(0 eVeV) to a state with an energy of 3.40 eVeV.

What is the speed of the electron after the collision?

Express your answer in meters per second.

Answer #1

A small, 200 gg cart is moving at 1.90 m/sm/s on a frictionless
track when it collides with a larger, 5.00 kgkg cart at rest. After
the collision, the small cart recoils at 0.810 m/sm/s .
What is the speed of the large cart after the collision?
Express your answer with the appropriate units.
