Figure (a) shows a red car and a green car that move toward each other. Figure (b) is a graph of their motion, showing the positions xg0 = 250 m and xr0 = −35 m at time t = 0. The green car has a constant speed of 22 m/s and the red car begins from rest. What is the acceleration magnitude of the red car? (a) (b) Number Units m/s

Samples A and B are at different initial temperatures when they are placed in a thermally insulated container and allowed to come to thermal equilibrium. Figure (a) gives their temperatures T versus time t. Sample A has a mass of 4.73 kg; sample B has a mass of 1.28 kg. Figure (b) is a general plot for the material of sample B. It shows the temperature change ΔT that the material undergoes when energy is transferred to it as heat Q. The change ΔT is plotted versus the energy Q per unit mass of the material, and the scale of the vertical axis is set by ΔTs = 4.20∘C. What is the specific heat of sample A? (a) (b) Number Units

Two spheres are each rotating at an angular speed of 22.0 rad/s about axes that pass through their centers. Each has a radius of 0.520 m and a mass of 1.57 kg. However, as the figure shows, one is solid and the other is a thin-walled spherical shell. Suddenly, a net external torque due to friction (magnitude = 0.340 N⋅m) begins to act on each sphere and slows the motion down. How long does it take (a) the solid sphere and (b) the thin-walled sphere to come to a halt? Solid sphere Thin-walled spherical shell (a) Number Units (b) Number Units

In a judo foot-sweep move, you sweep your opponent's left foot out from under him while pulling on his gi (uniform) toward that side. As a result, your opponent rotates around his right foot and onto the mat. The figure shows a simplified diagram of your opponent as you face him, with his left foot swept out. The rotational axis is through point O. The gravitational force F→g on him effectively acts at his center of mass, which is a horizontal distance d = 25 cm from point O. His mass is 84 kg, and his rotational inertia about point O is 65 kg⋅m2. What is the magnitude of his initial angular acceleration about point O if your pull F→a on his gi is (a) negligible and (b) horizontal with a magnitude of 300 N and applied at height h = 1.4 m? Assume free-fall acceleration to be equal to 9.81 m/s2. (a) Number Units (b) Number Units
