Abullet of mass m is traveling to the left with a speed v when it embeds itself in a block of mass m. the block sits on a frictionless surface and is connected to a spring of stiffness k. what is the compression s of the spring when the bullet and block come to rest?

Acertain half-reaction has a standard reduction potential e_red^0 = -0.94 v. an engineer proposes using this half-reaction at the cathode of a galvanic cell that e must provide at least 1.00 v of electrical power. the cell will operate under standard conditions. a. is there a minimum standard reduction potential that the half-reaction used at the anode of this cell can have? b. is there a maximum standard reduction potential that the half-reaction used at the anode of this cell can have?
