100 lb boy stands at one edge of the skating board. The board is 6 ft long and weighs 60 lb. Initially, the boy and the board are at rest. The boy then walks 6 ft to the opposite end with a constant speed of 3 ft/s relative to the board. Neglect friction between the board and the ground. Find: (a) Speed of the board [5 pts], and (b) Displacement of the board [3 pts] just as the boy is about to step off.

A boy of mass mboy stands at the edge of a merry­ go­ round of radius R = 8.2 m and mass mmgr and both are initially at rest. The boy then walks along the edge of the merry ­go ­round. After walking a distance of 20 m relative to the merry ­go ­round, the boy finds that the merry ­go ­round has rotated through an angle of 11°. Find the ratio mboy /mmgr.

A small 10.0-g bug stands at one end of a thin uniform bar that is initially at rest on a smooth horizontal table. The other end of the bar pivots about a nail driven into the table and can rotate freely, without friction. The bar has mass 50.0 g and is 75 cm in length. The bug jumps off in the horizontal direction, perpendicular to the bar, with a speed of 20.0cm/s relative to the table. a- What is the...

Please answer all not understanding: 1. Volumetric expansion coefficients of simple materials are often well catalogued. However, the thermal expansion coefficient β of a human body is less well known. This could affect the human body\'s specific gravity and, therefore, measurements of its body/fat ratio. Suppose that a human body of weight w0 (on dry land) is placed on a scale while completely immersed in formaldehyde of temperature T1. Once the temperature increases by ΔT, the scale reading drops by...
