1.) Determine the relative speed of two cars moving with 60mph toward N and SE, respectively(see the motion diagram included below for the case when the cars start their motion from the same point, makes A in the schematic)

Z V1 = 60 mph V1 = 60 mph 4 V, = 60 mph U V, = 60 mph t = 3,600 s: Both cars are in point A. Car 1 travels N 60 miles, reaching point B. Car 2 travels SE 60 miles, reaching point C
