A weight is attached to a spring suspended from a beam. At time t = 0, it is pulled down to a point 8 cm above the ground and released. After that, it bounces up and down between its minimum height of 8 cm and a maximum height of 24 cm, and its height h(t) is a sinusoidal function of time t. It first reaches a maximum height 1.4 seconds after starting. (a) Follow the procedure outlined in this section to sketch a rough graph of h(t). Draw at least two complete cycles of the oscillation, indicating where the maxima and minima occur. (b) What are the mean, amplitude, phase shift and period for this function? (Use a phase shift with an absolute value less than the period.) mean 16 amplitude 8 phase shift ___ period 2.8 (c) Give four different possible values for the phase shift. (Enter your answers as a comma-separated list.) _______ (d) Write down a formula for the function h(t) in standard sinusoidal form; i.e. as in the…
You and a friend are raising a beam, but your friend's rope is too short so you lift him off the ground. At the current time, everything is static. The tension in your cord is 1045.6 N, the mass of the beam is 15 kg, and the mass of your friend is 85 kg. The length of the beam is 4.9 m, d = 3.9 m, theta = 43.5 degrees, phi = 62.5 degrees. If you choose the base of the beam as the origin, and the positive torque direction as counter-clockwise, what is the torque from your cord on the friend+beam system?
Angular Impulse and Momentum Principles To apply the principle of angular impulse and momentum to describe a particle's motion. The moment of a force about a point O, fixed in an inertial coordinate system, MO, and the angular momentum about the same point, HO, are related as follows: ∑MO=H˙O where H˙O is the time derivative of the angular momentum, HO=r×mv. Integrating this equation with respect to time yields the following equation: ∑∫t2t1MO dt=(HO)2−(HO)1 This equation is the principle of angular impulse and momentum, and it is often rearranged to its more familiar form (HO)1+∑∫t2t1MO dt=(HO)2 A centrifugal governor consists of a central rotating shaft that has two thin, pin-connected rods attached to it; a heavy sphere caps the end of each rod. (Figure 1) A centrifugal governor mechanically limits an engine's speed. A part of the engine turns the centrifugal governor, and if the speed exceeds a set amount, the height of the spheres decreases the driving force of the engine by…

2.A 31 kg skip attached to a steel rope on a crane is used to hoist bricks from the ground to the top of a construction site. The steel rope is wound onto a lifting drum with a diameter of 700 mm and rotational frequency of 52 revolutions per minute. The lifting drum is situated on the top floor which is 196 m high. How many seconds will it take to lift bricks, three quarters up the height of the building?

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?

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?
A Jello desert resting on a plate is starts wiggling when it is sheared to the side 0.5 cm as is set on the table. The desert is a rectangular prism with a square face 25.0-cm on a side and a height of 12.0 cm. A quick Google search reveals that the density of Jello is 1140 kg/m3 with shear modulus of 530 N/m2. What is its rate of oscillation? If the energy of oscillation is dissipated at the rate of 5.00 x 10-5 J per second how long will the block wiggle?
