Dear , please find the answers slide to the given question attached below
11. A 2000-kg car is accelerated from 0 m/s to 25 m/s in 8 seconds. a....
A 1000 kg sports car accelerates from 0 m/s to 30 m/s in 11. What is the average power of the engine?
A 1000 kg sports car accelerates from 0 m/s to 32 m/s in 11 s. what is the average power of the engine?
A 1000-kg car is accelerated from rest to 85 km/h in 10 s. Assuming that no mass is lost and the car accelerates on a flat, horizontal surface, what is the change of the total energy of the car? How much power is required to change this total energy? Would the total energy change and power required change if it were to accelerate in 5 s?
a 1500 kg car accelerates from 0 to 25 m / s in 21.0s. How much is the average power delivered by the engine? (1hp = 746 W)
A 3000 kg car goes from 0 to 70 miles per hour in 6 seconds. Assume all the work supplied by the engine goes into increasing the kinetic energy of the car. 1. If the engine is purely electrical (and 100% efficient), determine the electrical work supplied in kW.h by the engine battery. A kW.h of electricity costs about 25 cents (this is just for your information). (kWh) 2.If the engine is a gasoline powered engine, determine the fuel consumed...
6. Determine the power required for a 5000-kg car to accelerate from 5m/s to 20m/s in 10 seconds. (Show the formula and procedures.) 7. For a hydroelectric plant, a hydraulic turbine-generator is installed at the site below the free surface. The turbine drives a generator for electricity. The elevation difference between the two free surfaces is h = 60m. The mass flow rate of water is th = 300kg/s. The shaft power output from the turbine is W. = 87kW....
A 2500 kg car is accelerated from rest to 20.0 m/s on a distance of 120.0m. What force acted on the car during this motion?
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 1000 kg sports car accelerates from 0 m/s to 33 m/s in 12 s.What is the average power of the engine?
Your car has a mass of 2000 kg and on flat ground can accelerate from 0 to 80 mphs in 8.1 seconds. How steep should the driveway to your house be so the car won't roll back down.
