Vectors. Calculating Weight (N) of Plane with force and angle of take off

AI Thread Summary
The discussion focuses on calculating the weight of a plane during takeoff, where an upward force of 8445 N acts at an angle of 50.2 degrees. The plane rises with a constant vertical velocity while accelerating horizontally, indicating that the vertical acceleration is zero. The gravitational acceleration is given as 9.8 m/s², which is essential for determining the weight of the plane. The user expresses uncertainty about how to proceed with the calculations, particularly regarding the vertical component of the forces involved. Understanding the relationship between the forces and the plane's motion is crucial for solving the problem.

Homework Statement


On takeoff” refers to after the plane has left the ground.
On takeoff, the combined action of the air around the engines and wings of an airplane exerts a(n) 8445 N force on the plane, directed upward at an angle of 50.2◦ above the hori- zontal. The plane rises with constant velocity in the vertical direction while continuing to accelerate in the horizontal direction.
The acceleration of gravity is 9.8 m/s2 . What is the weight of the plane? Answer in units of N.

8445 N on take off. 50.2 degrees on take off. Fg=9.8


Homework Equations


Fnet=ma Fvector 1+Fvecotr 2=Fvector 1 +Fvector 2

The Attempt at a Solution



To get to vertical, the plane would have to travel 39.8 degrees higher (90). I do not know what to do from here.

Hey, I'm kind of new to physics, but it seems to me that the fact that the vertical component of velocity is constant tells you something about the acceleration in the vertical direction. I think that should help.
 
Thread 'Collision of a bullet on a rod-string system: query'
In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...
Thread 'A cylinder connected to a hanging mass'
Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
