If the coefficient of kinetic friction between an object with mass M = 3.00 kg and a flat surface is μk= 0.530, what force will cause the object to accelerate at 2.50 m/s2? The force is applied at an angle of θ = 30.0° a) Calculate the force.

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.
