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?

A professor's office door is 0.99 m wide, 2.2 m high, 4.2 cm thick; has a mass of 27 kg, and pivots on frictionless hinges. A "door closer" is attached to door and the top of the door frame. When the door is open and at rest, the door closer exerts a torque of 5.6 N*m. What is the moment of inertia of the door? If you let go of the open door, what is its angular acceleration immediately afterward?
Ів 00 WB WC DBC A LA WA P lc UBC Engineering A kid excitedly swings his foam cut-out hammer. If point P acts like a pin and the hammer rotates about kg that point, what is the moment of inertia of the hammer? The foam has a density of p = 150 and a uniform thickness of t = 0.5 cm. Assume each cut-out is a rectangular plate and the foam acts as a rigid body. m³ Plate A has a length 14 = 34 cm and width w₁ = 8 cm. Plate B has a length 13 = 8.5 cm and width wB = 30 cm. Plate C is identical to plate D, and has a length lc = 15 cm and width wc = 5 cm. Plate C and D are attached to plate B such that their centers line up. Ip = 0.00758 x (kg) - m²
Hitting a Golf Ball A golf ball is hit so that its height h in feet after t seconds is h(1) = =16r² + 64t. (a) What is the initial height of the golf ball? (b) How high is the golf ball after 1.5 seconds? (c) Find the maximum height of the golf ball. (d) What is the domain and range of h in the con- text of this application?
The plate of a record player with a moment of inertia of 0:015 kg m2 rotates freely at 33 rpm. If you slowly drop a 180-gram vinyl disc with a 30:48 cm diameter on the board, what will be the new angular speed? (N.B. In real life, the turntable motor forces the speed to always remain 33 rpm. In this problem, we act as if the engine did not exist. )

One of your employees is complaining of knee pain on the R. While assessing his workstation, you noted that from a sitting position (starting position: 90 deg flexion), the employee needs to exert a lot of effort to extend his right knee to 45 deg from the starting point. The length of the limb (from the tibial tuberosity to the heel area) is measured to be 38 cm. What now is the linear distance traveled by the limb from the initial position to 45 degrees of knee extension?
BY 1.20 cm 7. QIC A simple pendulum consists of a small object of mass 3.0 kg hanging at the end of a 2.0-m-long light string that is connected to a pivot point. (a) Calculate the magnitude of the torque (due to the force of gravity) about this pivot point when the string makes a 5.0° angle with the vertical. (b) Does the torque increase or decrease as the Figure P8.6 angle increases? Explain.
A person is 1.65 m tall. a. Calculate the difference in blood pressure between the feet and top of the head of this person. To make sense of your answer, convert your answer to the unit of atm (101325 Pa = 1 atm). The density of blood is Pblood = 1.06 × 10³ kg/m³. b. Consider a cylindrical segment of a blood vessel 2.00 cm long and 1.50 mm in diameter. What additional outward force would such a vessel need to withstand in the person's feet compared to a similar vessel in her head? c. Justify how you solved for the area of the blood vessel.
