5. A cycle accelerates from rest at a constant acceleration of 0.4m/s/s for 20 seconds then stops pedalling and slowed to standstill at constant deceleration over distance of 260m.
Calculate:
a. Distance travelled by cyclist in the first 20seconds
b. The speed of the cyclist at end of this time

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?
