At what range of speeds can a car safely make the, Ask an Expert

Academics

Q. An electron is fired at a speed vo=5.6 x 106 m/s and at an angle θ0 = -45o between two parallel conducting plates that are D = 2.0 mm apart. If the voltage difference between the plates is ΔV = 100V, determine (a) how close, d, the electron will get to the bottom plate and (b) where the electron will strike the top plate.

Q. A curve of radius 64 m is banked for a design speed of 100 km/h. If the coefficient of static friction is 0.30 (wet pavement), at what range of speeds can a car safely make the curve?
