Normal Force and Tension on suitcase strap

AI Thread Summary
To solve for the normal force and tension in the strap while pulling a 21.9-kg suitcase at a 46.1° angle, first, identify the forces acting on the suitcase, including gravitational force, normal force, tension, and friction. Since the suitcase moves at constant speed, the net force is zero, allowing for the application of Newton's laws. The normal force can be calculated by considering the vertical components of the forces, while the tension in the strap can be determined from the horizontal components and the coefficient of kinetic friction, which is 0.380. The calculations will yield specific values for both the normal force and tension. Understanding these forces is crucial for analyzing the dynamics of the suitcase movement.

At the airport, you pull a 21.9-kg suitcase across the floor with a strap that is at an angle of 46.1° above the horizontal. Calculate the normal force in the strap, given that the suitcase moves with constant speed and that the coefficient of kinetic friction between the suitcase and the floor is 0.380. Calculate the Tension in the strap.

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 hanged 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...
