Consider the flow field V ! =axt^i+b^j, where a= 1=4 s−2 and b= 1=3 m=s. Coordinates are measured in meters. For the particle that passes through the point ðx, yÞ=ð1, 2Þ at the instant t = 0, plot the pathline during the time interval from t = 0 to 3 s. Compare this pathline with the streakline through the same point at the instant t = 3 s

20 points! asap! a is known to be 6,500 feet above sea level; ab = 600 feet. the angle at a looking up at p is 20°. the angle at b looking up at p is 35°. how far above sea level is the peak p? find the height of the mountain peak to the nearest foot. height above sea level =
