Help A pool ball moving 1.33 m/s
strikes an identical ball at rest.
Afterward, the first ball moves
0.814 m/s at a 33.3° angle. What
is the x-component and y-component of the velocity
of the second ball?
(Hint: The balls have equal mass.)

Charge is distributed along the entire x-axis with uniform density λ. how much work does the electric field of this charge distribution do on an electron that moves along the y-axis from y = a to y = b? (use the following as necessary: a, b, ε0, λ, and q for the charge on an electron.)
