Chapter 11, Problem 65P
SSM WWW Two 2.00 kg balls are attached to the ends of a thin rod of length 50.0 cm and negligible mass. The rod is free to rotate in a vertical plane without friction about a horizontal axis through its center. With the rod initially horizontal (Fig. 11-57), a 50.0 g wad of wet putty drops onto one of the balls, hitting it with a speed of 3.00 m/s and then sticking to it. (a) What is the angular speed of the system just after the putty wad hits? (b) What is the ratio of the kinetic energy of the system after the collision to that of the putty wad just before? (c) Through what angle will the system rotate before it momentarily stops?

- 17-89. The "Catherine wheel" is a firework that consists of a coiled tube of powder which is pinned at its center. If the powder burns at a constant rate of 20 g/s such as that the exhaust gases always exert a force having a constant magnitude of 0.3 N, directed tangent to the wheel, determine the angular velocity of the wheel when 75% of the mass is burned off. Initially, the wheel is at rest and has a mass of 100 g and a radius of r=75 mm. For the calculation, consider the wheel to always be a thin disk.

Using a radar gun, she establishes that a sphere with a mass of 0.120 kg and diameter of 8.00 cm has its speed reduced by 10% due to air resistance when the initial speed is of 49.0 m/s as it travels from the launch site to the target a distance of 16.0 m away. Due to the air resistance, a change in temperature occurs initially only for the air in a cylinder equal to the volume of air swept out by the sphere. Determine the maximum possible temperature change (in °C) for this air when the temperature of the air is 20.0°C. To find the greatest possible temperature change, you may make the following assumptions: air has a molar specific heat of c- (R, an equivalent molar mass of 28.9 g/mol, and a density of 1.20 kg/m. 98.5 When finding the change in internal energy of the air, how can you find the number of moles of air?
