3. You are an insurance investigator called to the scene of a car accident. According to witnesses, a blue car (mass ms) was traveling south through an intersection when it was hit by a red car (mass m.) traveling east that ran a stop sign. You observe that the red car came to rest in the intersection. The blue car ended up a distance from the intersection, in a direction measured south of east. Determine the...

2. The electric vehicle Tesla Model S has a drag coefficient of 0.24, a mass of 2100 kg, and a frontal area of 2.4 m2. The coefficient of rolling resistance of its tires is 0.01. Recall the density of air at sea level is 1.3 kg/m3. How much kinetic energy is required to overcome rolling resistance and air resistance (drag) at Autobahn speeds of 180 km/hr for a 200 km trip? How much useful energy (in MJ) and money (in...

Consider a concentric tube heat exchanger with hot and cold water inlet temperatures of 202 and 35°C respectively. The flow rates of the hot and cold fluids are 42 and 84 kg/h, respectively. Assume the overall heat transfer coefficient is 178 W/m2k. cc = 4186 J/kgk, ch = 4302 J/kgK What is the maximum heat transfer rate that could be...

1) Planet Velocities and Energy (33 pts) We talked about how planet formation involves the collisions of bodies (planetesimals, embryos) leading to the growth (and heating) of a planet. Let's think about the velocities and energies involved here. a) The speed of a body in its orbit around the Sun is given by the equation: Here Vis the speed of the body in m/s, G is the gravitational constant,...
