Q1. A uniform, upward-pointing electric field E of magnitude 3.5×10^3 N/C has been set up between two horizontal plates by charging the lower plate positively and the upper plate negatively. The plates have length L = 5 cm and separation d = 2.00 cm. Electrons are shot between plates from the left edge of the lower plate.

The first electron has the initial velocity v0 that makes an angle θ=45° with the lower plate and has a magnitude of 7.53×106 m/s. would this electron strike one of the plates? If so, what is the horizontal distance from the left edge? If not enter the vertical position at which the particle leaves the space between the plates.

Q2. At one instant a bicyclist is 45.0 m due east of a park's flagpole, going due south with a speed of 20.0 m/s. Then 19.0 s later, the cyclist is 45.0 m due north of the flagpole, going due east with a speed of 20.0 m/s. For the cyclist in this 19.0 s interval, what are the (a) magnitude and (b) direction of the displacement, the (c) magnitude and (d) direction of the average velocity, and the (e) magnitude and (f) direction of the average acceleration?
