Consider a Porsche 911 sports car with a mass of 1900 kg. The air drag force at highway speeds can be approximately calculated as: F_drag = 1/2 C p Av^2 where p = 1.2 kg/m^3 is the density of air, A is the front area of the car, C is the drag coefficient and v is the velocity. For the Porsche 911, we can take A - 2.3 m^2 and C = 0.28. What is the power necessary to overcome...

Problem 2 (40%). While driving, some of a car's kinetic energy is lost to air drag. We would like to estimate the importance of air drag using dimensional analysis and the Buck- ingham a theorem. The relevant parameters are the drag force (FD), the frontal surface area (A) and velocity of the car (v), as well as the density of air (Pair = 1 kg/m3). Answer the following questions: 1. Derive the expression of the drag force as a function...

A wagon is moving with a velocity of -2.0 m/s while having a 20 kg mass on top of it. There is a force applied to the wagon over a distance of 1.25 m. It then comes to a stop with a velocity of 0m/s. Please answer the questions. Show all work. 1. What is the total work done on the wagon? 2. What was the average force applied to the box to bring it to a halt?

A 1000 kg race car starts from rest and reaches a speed of 100 km/h in 20 s. What is the power delivered by the car’s engine? (2 points). A 1 kg mass is released from the top of a smooth slide of height 2m. At the bottom of the slide the mass slides on a horizontal surface and stops at a distance of 5 m. What is the coefficient of kinetic friction of the horizontal surface? (3.5 points). The...
