A block is placed at the bottom of an incline. Its connected by a string that is running through a pulley, a second mass which hangs vertically at the top of the incline. The mass at the bottom is 3kg, and the mass hanging at the top is 5kg.
The incline is at angle of 20 . There is a coefficient of kinetic friction
between the incline and the first block of 0.13. The base of the incline is 10m long. The system is released from rest.

1. Draw free body diagrams for both blocks at the moment of release
2. Calculate the tension and acceleration of the system
3. How fast is the hanging block moving just before it strikes the ground

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?
