Q1 and 2

Solve each problem in the space provided, showing all work and using diagrams where possible. All numerical results should be stated to 3.00 or 4.000 significant figures and in mks units unless otherwise noted. For additional space use the back of this sheet. 1. You are lying in the grass with your head on the midpoint of a line connecting the bases of two telephone poles exactly 35.2 m apart. Both telephone poles are vertical and 12.0 m high. A large jet is traveling horizontally in a straight line with a ground speed of 415 mph. If from your perspective the jet flies from a point in line with the top of one pole to a point in line with the top of the other pole in 19.4 s, what is the altitude of the plane in mks units? Is your answer reasonable? 2. A locomotive leaves a train station with the magnitude of its displacement along a straight track given by 5= (1.4- \"}]f"'. Exactly 10 s later, another locomotive on a parallel track passes the station with constant velocity. What minimum velocity must the second locomotive have so that it just catches the first locomotive without passing it? (Hint: plot displacement versus time for both locomotives assuming the station is at s = 0.)
