Figure 3 shows a pendulum (a 2m long massless string suspended from the ceiling, on the other end of which is a 50g mass) at an initial release angle and initial velocity (see figure). a. What angle is the pendulum at (as measured from the dotted vertical line in figure 3) when it's at rest? b. Go to figure 3 and label the places where KE is maximum, KE is minimum, PE is maximum, and PE is minimum. c. How much work does gravity do, from the point when the pendulum is released in figure 3 to the point when it is at rest in part a? d. Find the magnitude of the impulse on the pendulum, again between the point when the pendulum was released (figure 3) and the point when it is at rest.

In the figure below, two applied forces are acting at point C where there is a 120 lb and let P = 150 lb. Find the unknown forces/tensions in bar AC and BC that are reacting. Do not forget the free-body diagram, units, and vector notation.
An object consists of four small spheres attached to the ends of two thin rods that are connected perpendicularly at their centers, forming a cross. Assume each sphere has a mass of m and a radius that is negligible compared to the distance R that each is from the cross’s center (in other words, we can model each as if it were a particle), and that each rod has a mass of m/2. What is a for this object for rotations around an axis perpendicular to the plane of the cross is _____ for rotations around an axis that goes along one of the rods is _____ (Hint: The object’s total mass is not m.)
Figure 2 shows a two degree of freedom mass spring system. Use Newton’s second law to derive the equation of motion of this system, express this in matrix form.
I just really know where exactly to start with this I think the tension is equal to the masses E and D and the force keeping the system in equalibrium but I don't know how I can use the tension to solve for the distance s If you could just give me somewhere to start that would be good
The shaft in the figure, carrying three unbalanced masses, is rotating at a constant speed hızla = 10 r / s. Find the balancing values (kg.mm) and their positions in case of balancing in DI and DII planes.

An ideal spring, with a pointer attached to its end, hangs next to a scale. With a 100 N weight attached, the pointer indicates "40" on the scale as shown. Using a 200N weight instead results in "60" on the scale. Using an unknown weight X results in "30" on the scale. The weight X is: Hint: Draw the force - Displacement diagram. 100 N O 1.20 N O 2.30 N O 3.40 N O 4.50 N O 5.70 N
Drop-load (III) context We want to lower a suspended load in a controlled way, so that it hits the ground with a speed whose modulus is not too great. To do this, the suspended load (B) is connected by a rope passing through a pulley to another mass (A), which can move on an inclined surface. Information The masses of charges A and B are known.The pulley is a solid cylinder (or disc) of mass mp and radius R which can turn without friction.The surface on which mass A is placed is horizontal.There is friction between mass A and the surface on which it is placed, the coefficient of friction is uc.Mass A is on a surface tilted by an angle delta.The rope attached to mass A is perfectly parallel to the surface on which the mass is placed. Modelization Create a model for the acceleration of mass B given the known parameters of the problem that are relevant. Mass of load A: 70kg; Mass of the suspended load (B): 82kg; Pulley mass (mp): 52kg Pulley radius: 0.46m Coefficient of friction: 0.12…
