The speed needed to escape the pull of Earth's gravity is 11.3 km/s. What is this speed in mi/h? (1 mile = 1609 m)

The value of the speed needed to escape the pull of Earth's gravity in miles per hour (mi/h) is 25282.8.

Given the following data;

In this exercise, you're required to convert the value of the speed needed to escape the pull of Earth's gravity in kilometer per seconds (km/s) to miles per hour (mi/h).

Conversion:

1 mile = 1.609 kilometer

X mile = 11.3 kilometer

Cross-multiplying, we have;

× X =

X = 7.0230 miles

Since we know that one (1) hour is equal to 3600 seconds, we would multiply the value of X by 3600 in order to convert it to miles per hour (mi/h).

X = 7.0230 × 3600

X = 25282.8 mi/h

Therefore, the value of the speed needed to escape the pull of Earth's gravity in miles per hour (mi/h) is 25282.8.

11.3 km/sec * 1000 m/km / 1609 m/mi = 7.02 mi / sec

7.02 mi/sec * 3600 sec / hr = 25,300 mph

object 2 because all the other ones are wrong

c because the action was the roller coaster reaches bottom of hill (action) reaction would be blood tends to drain away from head

hope this !
