Amotorist drives north for 35.0 minutes at 85.0 kph. he then stops for 15.0 minutes. the motorist then drives 130.0 km in 2.0 hours. calculate the average velocity of the motorist if the second leg of the trip a. was north b. was south

A. 216.36

B. 96.56

Explanation:

Let be the distance in first part.

= velocity × time

= 85 ×

= 49.58 km

Let be the distance in first part.

= 130 km

Average velocity =

When second leg of the trip is

A. Toward north

Average velocity = }{Total time}  " alt=" s_{1} + s_{2}" />}{Total time}  " />

Average velocity =

Average velocity =216.36

B. Toward south

Average velocity = }{Total time}  " alt=" s_{1} - s_{2}" />}{Total time}  " />

Average velocity =

Average velocity =96.56

they are non-matter

explanation:

they are non-matter. basically, any type of energy or any abstract concept is an example of something that does not matter. other examples include dreams, magnetism, radio, and hate
