Over the interval from 4 seconds to 10 seconds, the object's speed was calculated to be 3 m/s. what is the object's position after 8 seconds have elapsed.

1 meter farther

Step-by-step explanation:

The difference in time from 4 seconds to 10 seconds is 6 seconds.

The speed is half of the difference of time.

That is why the speed is 3 m/s.

The difference in time from 10 to 18 is 8 seconds.

Take the time and divide it by 2 to get the speed.

The speed is 4 m/s.

The object's position is 1 more meter.

4 m/s - 3 m/s = 1 m/s

reduce the friction between its moving parts

step-by-step explanation:

in fact, by reducing the friction between the moving parts of the machine, it is possible to reduce the energy wasted due to this friction; therefore, more input energy is converted into useful work, and this will improve the efficiency of the machine.
