The fraction of energy that is lost is 25%, it depends how fast the ball was going until it lost 25% of its energy, the gravitational energy was transferred into the kinetic energy that helped the ball bounce back

What type of OS is very fast and small, and is often embedded, or built into the circuitry of a device?
Bezzdna [24]

Answer:

Real time operating system (RTOS)

Explanation:

  • Real time operating system is an operating system software which is used for the real-time applications that processes the data as soon as the input comes to the system.

It is very fast because it processes the data without any buffer delays.

  • In RTOS the scheduler provides a deterministic time which is predicted for the execution pattern. In a real-time operation the system must respond to each sequence of execution within a certain time frame which is the deadline for the operation so that the next inline process can be executed. Hence it is used in embedded systems and circuitry devices.

Determine the centripetal force on a vehicle rounding a circular curve with a radius of 80 m at a constant speed of 90 km/h if t
quester [9]
Mass of the vehicle = 2000 kg
Velocity of the vehicle = 90 km/hr
                                   = 25 m/s
Radius of the curve = 80 m
Then
Centripetal force = [2000 * (25)^2]/80
                            = (2000 * 625)/80
                            = 15625 kg m/s
                            = 15625 Newton second
