Sheila has just arrived at the airport and is dragging her suitcase to the luggage check-in desk. She pulls on the strap with a force of 190 N at an angle of 35° to the horizontal to displace it 45 m to the desk. If the mass of her suitcase is 20 kg ,what is the speed of the suitcase when it reaches the check -in desk.
A carousel has a radius of 1.70 m and a moment of inertia of 130 kg · m2 . A girl of mass 46.5 kg is standing at the edge of the carousel, which is rotating with an angular speed of 3.20 rad/s. Now the girl walks toward the center of the carousel and stops at a certain distance from the center d. The angular speed of the carousel is now 5.2 rad/s. How far from the center did the...

Now the girl walks toward the center of the carousel and stops at a certain distance from the center d. The angular speed of the carousel is now 5.0 rad/s. How far from the center did the...
A carousel has a radius of 2 m and a moment of inertia of 500 kg·m², and can rotate around a frictionless axis. A person of 25 kg runs tangentially towards the edge of this carousel, which is at rest, with an initial velocity v = 2.5 m/s, and jumps into the toy. What is the final angular velocity of the person and the carousel together?
A 10kg lost baby is stuck sitting on a carousel that has a 20 M radius. If the Carousel is rotating at a constant speed of 8m/s, what is the Magnitude of the static friction force?
A electric model train travels at 34.7 cm/s around a circular track of radius 1.67 m. How many revolutions does it perform per second, i.e, what is the motion\'s frequency? Find the train\'s period of revolution.
Another bicycle, also with 0.3 m radius wheels, is moving such that the angular speed of each wheel is 75 rad/s. If the bicyclist then applies the brakes and the wheels slow with a constant angular acceleration of -15 rad/s2, how many revolutions will each wheel make before the bike stops
