Use Ko+Uo+W NCF=Kf+U f Answer the following questions about the system as the mass descends and the glider moves. Use only symbols (M1, mh, g, H1, vo, vf) in your response and list: a) The glider’s initial kinetic energy relative to the tabletop. b) The glider’s final kinetic energy relative to the tabletop. c) The mass hanger’s initial gravitational potential energy relative to the floor. d) The mass hanger’s final gravitational potential energy relative to the floor. e) The mass hanger’s initial kinetic energy relative to the floor. f) The mass hanger’s final kinetic energy relative to the floor.

25pts the diagram shows the positions of the sun, moon and earth during spring tides, when the high tides are at their highest and low tides at their lowest. what is it about these positions that causes these high and low tides?

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?
