1.) A thin, rectangular sheet of metal has mass M and sides of length a and b. Find the moment of inertia of this sheet about an axis that lies in the plane of the plate, passes through the center of the plate, and is parallel to the side with length b.
I = ?
2.) Find the moment of inertia of the plate for an axis that lies in the plane of the plate, passes through the center of the plate, and is perpendicular to the axis in part A.
What is the attractive force between the protons. A rocket rises vertically, from rest, with the acceleration of 3.0 m/s2 until it runs out of fuel at an altitude of 1100 m. After this point, its acceleration is that of gravity, downward.
Light from a He-Ne laser (= 632.8) strikes a pair of slits at normal incidence, forming a double-slit interference pattern on a screen located 1.10 from the slits. The figure shows the interference pattern observed on the screen.
A skier (m=63.0 kg) starts sliding down from the top of a ski jump with negligible friction and takes off horizontally. If h = 6.10 m and D = 12.2 m, find H.
A pot of hot water is boiling on your stove. The pot is in the shape of a round cylinder made of aluminum which is 10 cm in radius. The aluminum is 3 mm thick. You notice that after 25 minutes.
An electron and a positron each of mass 9.1 x 10^-31 kg, are in the same general vicinity and have very small initial speeds
A 20 g ball is fired horizontally with initial speed v_0 toward a 110 g ball that is hanging motionless from a 1.10 m-long string. The balls undergo a head-on, perfectly elastic collision, after which the 110 g ball swings out to a maximum angle t..
Find out the intensity if the frequency is increased to 2.90 kHz while constant displacement amplitude is maintained.
A child suddenly runs into the street. If it takes the driver 0.80 s to react and apply the brakes, explain how many meters will the car have moved before it begins to slow down?
The maximum transverse acceleration of a point at the middle of the segment is 8800 m/s^2 and the maximum transverse velocity is 3.50m/s.
Calculate the speed of a proton after it accelerates from rest through a potential difference of 170V, Calculate the speed of an electron
A small object with a mass of 360 mg carries a charge of 30.0 nC and is suspended by a thread between the vertical plates of a parallel-plate capacitor. The plates are detached by 2.40 cm. If the thread makes an angle of 17.0° with the vertical, what..
