Ladybugs on a Rotating Disk
Two ladybugs sit on a rotating disk, as shown in the figure (the ladybugs are at rest with respect to the surface of the disk and do not slip). Ladybug 1 is halfway between ladybug 2 and the axis of ...

Continue readingA sign is to be hung from the end of a thin pole, and the pole supported by a single cable. Your design firm brainstorms the six scenarios shown below. In scenarios A, B, and D, the cable is attached ...
Continue readingTwo identical uniform solid spheres are attached by a solid uniform thin rod, as shown in the figure. The rod lies on a line connecting the centers of mass of the two spheres. The axes A, B, C, and D ...
Continue readingThe abstract sculpture shown in the figure can be placed on a horizontal surface without tipping over. Different parts of the sculpture may be hollow or solid, or made of different materials, but the artist isn’t revealing any such information.
Continue readingSix roller-coaster carts pass over the same semicircular “bump.” The mass M of each cart (including passenger) and the normal force n of the track on the cart at the top of each bump are given in the figures. Rank the speeds of ...
Continue readingLearning Goal: To understand Newton’s law of universal gravitation and be able to apply it in two-object situations and (collinear) three-object situations; to distinguish between the use of G ...
Continue readingA) A small car of mass m and a large car of mass 4m drive along a highway. They approach a curve of radius R. To not slip, both cars need to maintain a net force of F as they travel around the curve. ...
Continue readingA roller-coaster track has six semicircular “dips” with different radii of curvature. The same roller-coaster cart rides through each dip at a different speed For the different values ...
Continue readingLearning Goal: To understand and use inverse-square relationships. Two quantities have an inverse-square relationship if y is inversely proportional to the square of x. We write the mathematical relationship as y = A/x2. Here, A is a constant. This relationship is sometimes written as
Continue readingA road race is taking place along the track shown in the figure . All of the cars are moving at constant speeds. The car at point F is traveling along a straight section of the track, whereas all the ...
