Acomet is traveling through space with a speed of 3.40 ✕ 104 m/s when it collides with an asteroid that was at rest. the comet and the asteroid stick together during the collision process. the mass of the comet is 1.05 ✕ 1014 kg, and the mass of the asteroid is 7.05 ✕ 1020 kg.
a. what is the speed of the center of mass of the asteroid-comet system before the collision?
b. what is the speed of the system's center of mass after the collision?

Along wire of diameter 1 mm is submerged in an oil bath of temperature ∞ 31°c. the wire has an electrical resistance per unit length of 0.01 ω/m. if a current of 103 a flows through the wire and the convection coefficient is 500 w/m2·k, what is the steady-state temperature of the wire? from the time the current is applied, how long does it take for the wire to reach a temperature that is within 1°c of the steady-state value? the properties of the wire are 8000 kg/m3, 500 j/kg·k, and 20 w/m·k.
