What is the speed of a car going v=1.000mph in si units? notice that you will need to change from miles to meters and from hours to seconds. you can do each conversion separately. use the facts that 1mile=1609m and 1hour=3600s. express your answer i

The appropriate solution is "0.4469 m/s". A further explanation is provided below.

According to the question,

Given facts:

The speed of the car will be:

=

By substituting the above given values, we get

=

=

=

Thus the above solution is correct.

0.4469 m/s

Explanation:

First, convert mile into meters.

1 mile = 1609 m

Secondly, convert hour into seconds

1 hour = 3600 s

Finally, convert 1.000 mph to meters per second.

1.000 mph is same as 1 mile / 1 hour

Put SI units we converted earlier.

1 mile / 1 hour = 1609 m / 3600 s

1 mile / 1 hour = 0.4469 m/s

half of a circle
