Suppose a 65 kg person stands at the edge of a 6.5 m diameter merry-go-round turntable that is mounted on frictionless bearings and has a moment of inertia of 1850 kg m2. The turntable is at rest initially, but when the person begins running at a speed of 3.8 m/s (with respect to the turntable) around its edge, the turntable begins to rotate in the opposite direction. Calculate the angular velocity of the turntable
An abstract sculpture is constructed by suspending a sphere of polished rock along the vertical with four cables connected to a square wooden frame 1.1 m on a side. If the stone has mass m = 7.5 kg, and the bottom two cables are under a tension of..
If the bullet leaves the gun at a speed of 280 m/s, by how much will it miss the target? Illustrate at what angle should the gun be aimed so as to hit the target?
A Wheatstone bridge is connected to a nine volt battery and is balanced when R1 = 6.3 k?, R2 = 3.3 k?, and R3 = 9.7354 k?
Determine the tension T in the string.
With a particular grating a doublet of the two wavelengths 731.3 and 732.1 nm is viewed in the third order at 9.3° to the normal, find the grating spacing in nanometers
An airplane is flying in a horizontal circle at the speed of 542 km/h. If the wings of the plane are tilted 33.0° to the horizontal, what is the radius of the circle in that the plane is flying? Suppose that the required force is provided entirely by..
Automobile Airbags. The human body can survive an acceleration trauma incident (sudden stop) if the magnitude of acceleration is less than 250m/s2.
The two forces in each pair could have different physical origins (for instance, one of the forces could be due to gravity, and its pair force might be due to friction or electric charge).
A 67.00 kg person on skis is going down a hill sloped at 30° from the horizontal. The coefficient of friction between skis and snow is 0.19. What would be the magnitude of the acceleration.
In a charming 19th-century hotel, an old-style elevator is connected to a counterweight by a cable that passes over a rotating disk 3.50 m in diameter. The elevator is raised and lowered by turning the disk, and the cable does not slip on the rim ..
A ball is thrown toward a cliff of height h with a speed of 30m/s and an angle of 60? above horizontal, What was the maximum height of the ball
The objects are then released from rest. Assuming that the particles never reach the pulley, and also that the particles do not rebound when they strike the ground.
