Apowerful motorcycle can accelerate from rest to 26.8 m/s (60 mi/h) in only 3.90 s. (a) what is its average acceleration in m/s^2? m/s^2 (b) how far does it travel in that time? m

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.

Which lists the pairs of plates in order from least to greatest in terms of the work done to move the electron?

What is the coefficient of kinetic friction μk between the block and the tabletop?
