Fundamental.9 deals with the equation of motion. The use of the equation of motion to solve this problem is mandatory. Solution using other approaches (conservation of energy...) will be automatically considered false.For the problem related to Fundamental.9 sketches of the system showing:• the respective velocity and acceleration and the frame of reference considered• the forces acting on the system of considered, in other words, a free body diagram (FBD)are mandatory. Their absences will automatically make the problem false.The uniform 19 lb beam is initially at rest when the forces FA applied at A (on its left hand-side) is vertical and FB applied at B (on its right hand-side) forms an angle 0=56° with the horizontal.FAFBAВ.B012 ftDetermine FA (answer in the cell bellow) and FB to make sure that:• the beam has no angular acceleration• its horizontal horizontal acceleration is 1.6-times smaller than its vertical acceleration

A point charge q1 = +5.00 micro Coulomb is held fixed in space. From a horizontal distance of 6.00 cm, a small sphere with mass 4.00 x 10-3 kg and charge q2 = +2.00 micro Coulomb is fired toward the fixed charge with an initial speed of 40.0 m/s. Gravity can be neglected. What is the acceleration (in m/s2) of the sphere at the instant when its speed is 25.0 m/s?
Subject: Dynamics of Rigid Bodies
Topic: Dynamics of Rigid Bodies Question: From the problem below, derive an equation for dθ/dt in terms of t, considering θ as the angle relative to the ground at which the camera is positioned to film the rocket. As the rocket starts to launch, a news van starts to accelerate away from the position of the rocket launch pad to obtain a different view of the rocket as it flies. Suppose that initially, the news van is 400 m away from the launch pad, it has an initial velocity of 5 m/s and an acceleration of 3.5 m/s 2 . Determine the velocity and acceleration of the rocket relative to the van 4 seconds after the launch.
A velocity of a vehicle is required to be controlled and maintained constant even if there are disturbances because of wind, or road surface variations. The forces that are applied on the vehicle are the engine force (u), damping/resistive force (b*v) that opposing the motion, and inertial force (m*a). A simplified model is shown in the free body diagram below. From the free body diagram, the ordinary differential equation of the vehicle is: m * dv(t)/ dt + bv(t) = u (t) Where: v (m/s) is the velocity of the vehicle, b [Ns/m] is the damping coefficient, m [kg] is the vehicle mass, u [N] is the engine force. Question: Assume that the vehicle initially starts from zero velocity and zero acceleration. Then, (Note that the velocity (v) is the output and the force (w) is the input to the system): 1. What is the order of this system?

Five masses m1, m2, m3 m4 and m5 are 150 kg, 250 kg, 190 kg , 120 kg and 210 kg respectively. The corresponding radii of rotation are 0.2 m, 0.15 m, 0.25 m 0.1 and 0.3 m respectively and the angles between successive masses are 45°, 75° 20 and 110°. Find the position and magnitude of the balance mass required, graphically, if its radius of rotation is 0.25 m
Zorch, an archenemy of Superman, decides to slow Earth’s rotation to once per 29 h by exerting a force parallel to the equator, opposing the rotation. Superman is not immediately concerned, because he knows Zorch can only exert a force of 4.15 × 107 N. For the purposes calculations in this problem you should treat the Earth as a sphere of uniform density even though it isn't. a. How long, in seconds, must Zorch push with this force to accomplish his goal? (This period gives Superman time to devote to other villains.)
Dynamics Question A ball with a mass of .5kg is attached to a 1m string. The string is attached to a post and is free to rotate. The string can be assumed to be weightless and not stretch. The ball is spun around the post in the horizontal plane (so gravity is perpendicular to the string and direction of motion) at a rate of 2π radians per second and that is slowing down by .2 rad/s^2. What is the total acceleration vector and the tension in the string?
Dynamics of Rigid Bodies Problem: 1.) A diver jumps from a height of 3.0 metres above the height of the water and touches the surface 1.0 s later. What was his velocity when he hit the water? 2.) A motorcyclist, travelling at a speed of 30 m/s, sees an obstacle 100 metres in front of him and puts on the brakes. He hits it 5.0 seconds later. If the motorcycle slows down uniformly, how fast was it going at the instant of the collision?
