A bullet in a gun is accelerated from the firing chamber to the end of the barrel at an average rate of 5.70 x 10^5 m/s^2 for 9.

60 x 10^−4 s. What is its muzzle velocity (in m/s) (that is, its final velocity)? (Enter the magnitude.)

Answer:

Final speed, v = 547.2 m/s

Explanation:

Initial velocity of the bullet, u = 0

Acceleration of the bullet, a=5.7\times 10^5\ m/s^2

Time taken, t=9.6\times 10^{-4}\ s

Let v is the final velocity of the muzzle. It can be calculated using the first equation of motion as :

v=u+at

v=at      

v=5.7\times 10^5\ m/s^2\times 9.6\times 10^{-4}\ s    

v = 547.2 m/s

So, the final speed of the muzzle is 547.2 m/s. Hence, this is the required solution.

The engine in your car is sometimes called: A. A 2-stroke engine
Juli2301 [7.4K]

Answer:A

Explanation:

Engines in car are 4 stroke engine . A 4-stroke engine is internal combustion engine which derives its power by four piston strokes . Internal combustion means combustion takes inside the engine i.e. is in cylinder.

There are process in 4 stroke engine

  • Intake: Intake of air
  • Compression:compression of intake air to a high pressure
  • Combustion:Fuel is injected and burned to get power
  • Exhaust:removal of exhaust gases after combustion
