A box is sliding across a floor at a velocity of +7 m/s when it begins to slow down (decelerate). The box achieves a new velocity of +1 m/s. in 12 seconds. Calculate the box’s rate of acceleration.

Suppose a diode consists of a cylindrical cathode with a radius of 6.200×10^−2 cm , mounted coaxially within a cylindrical anode with a radius of 0.5580 cm . the potential difference between the anode and cathode is 260 v . an electron leaves the surface of the cathode with zero initial speed (v initial=0). find its speed vfinal when it strikes the anode.
