B. draw a distance-time graph of fred's 1
1. fred goes on a train for 3 hours, from
baltimore to nyc for a meeting,
covering 120 miles.
2. fred stops in nyc and sits down for
his meeting for 3 hours, talking to his
partners.
distance from home

3. fred returns to baltimore on a fast
train taking 2 hours.
time (hours)
4. what is fred's velocity for the first 3 hours of his ride?

An charge with mass m and charge q is emitted from the origin, (x,y)=(0,0). a large, flat screen is located at x=l. there is a target on the screen at y position y(h), where y(h) > 0. in this problem, you will examine two different ways that the charge might hit the target. ignore gravity in this problem. 1.assume that the charge is emitted with velocity v(0) in the positive x direction. between the origin and the screen, the charge travels through a constant electric field pointing in the positive y direction. what should the magnitude e of the electric field be if the charge is to hit the target on the screen? express your answer in terms of m, q, y(h), v(0), and l. 2.now assume that the charge is emitted with velocity v(0) in the positive y direction. between the origin and the screen, the charge travels through a constant electric field pointing in the positive x direction. what should the magnitude e of the electric field be if the charge is to hit the target on the screen? express your answer in terms of m, q, y(h), v(0), and l.
