The engine in an imaginary sports car can provide constant power to the wheels over a range of speeds from 0 to 70 miles per hour (mph). At full power, the car canaccelerate from zero to 32.0 mph in time 1.50 s.
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...
A car with a power rating of 75 hp can accelerate from 0-60 mph in 10 seconds. How long would it take a car of power rating of 240 hp to accelerate by the same amount? Which car performs more work?

Constant acceleration motion A car can go from 0 to 60 mph is 12 s. A second car is capable of twice the acceleration of the first car. Assuming that it could maintain the same accel higher speeds, how much time will this second car take to go from 0 to 120 mph? eration at
Constant acceleration motion 8. (10 pts) A car can go from 0 to 60 mph is 12 s. A second car is capable of twice the acceleration of the first car. Assuming that it could maintain the same acceleration at higher speeds, how much time wl this second car take to go from 0 to 120 mph?
A high-performance sports car can go from 0 to 100 mph in 5.6 s. (Assume the car travels in the positive direction. Indicate the direction with the sign of your answer.) (a) What is the car's average acceleration (in SI units; meter-kilogram-second)? (b) The same car can come to a complete stop from 31 m/s in 5.9 s. What is its average acceleration?
1-C 2-E can you give me the code for these two questions? Physics 1210 Homework 1 Written-out problems 1. X A truck traveling at 56 km/h (15.5 m/s) is 35 m from a wall when the driver hits the brakes. Four seconds later the car hits the wall. a) what was the truck's acceleration before impact? b) how fast was the truck traveling at impact? c) draw graphs of position versus time, velocity versus time, and acceleration versus time for...
Dr. C. #2. (PHYS 121 engineering design exercise) You have seen why cars inherently accelerate quicker in a straight line and have better fuel mileage than an SUV with the same engine; it's because of air drag and the smaller frontal area and better drag coefficient of the car. Now let's think about why cars handle (take turns, change lanes and make other quick maneuvers) better than an SUV. We'l1 simplify our analysis by considering a vehicle of mass M...
