What is the kinetic energy of an 80.0 kg football player running at 6.0 m/s?

a)240 j
b)480 j
c)1400 j
d)2900 j

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.)
