A person sees the image of an arrow reflected in a plane mirror. The dashed line in the figure represents the vertical center of the mirror. The person uses an opaque sheet to cover half of the mirror. A vertical mirror with the vertical center marked. The object is an upright arrow some distance in front of the upper half of the mirror. The base of the arrow is a small distance above the vertical center mark of the mirror. A face is in front of the lower half of the mirror and closer to the mirror than the arrow. The eye in the face is approximately the same distance below the vertical center of the mirror as the tip of the arrow is above the vertical center.
In which case will the person still see the image of the arrow?

1134567 a jet with mass m = 1.1 ă— 105 kg jet accelerates down the runway for takeoff at 2 m/s2. 1) what is the net horizontal force on the airplane as it accelerates for takeoff? 2.2*10^5 n your submissions: 2.2*10^5 computed value: 220000submitted: saturday, january 26 at 2: 41 pm feedback: correct! 2) what is the net vertical force on the airplane as it accelerates for takeoff? 0 n your submissions: 0 computed value: 0submitted: saturday, january 26 at 2: 41 pm feedback: correct! 3) once off the ground, the plane climbs upward for 20 seconds. during this time, the vertical speed increases from zero to 21 m/s, while the horizontal speed increases from 80 m/s to 95 m/s. what is the net horizontal force on the airplane as it climbs upward? n 4) what is the net vertical force on the airplane as it climbs upward? n 5) after reaching cruising altitude, the plane levels off, keeping the horizontal speed constant, but smoothly reducing the vertical speed to zero, in 13 seconds. what is the net horizontal force on the airplane as it levels off? n 6) what is the net vertical force on the airplane as it levels off?
