Arunner starts jogging with an initial velocity of 0.85 m/s and eventually reaches with a final velocity of 5.2 m/s. this change in velocity occurs over a displacement of 12.0 m. what is his acceleration?

The answer to your question is:      a = 1.1 m/s²

Explanation:

Data

v1 = 0.85 m/s

v2 = 5.2 m/s

displacement = 12.0 m

a = ?

Formula

                v2² = v1² + 2ad

                a = (v2² - v1²) / 2d

Process

              a = (5.2² - 0.85²) / (2)(12)

              a = (27.04 - 0.72) / 24

              a = 26.32 / 24

              a = 1.1 m/s²

explanation:

explanation:

earth's surface is mainly heated by the absorption of infrared radiation from the sun.

evaporation occurs because molecules in liquid water are warmed ( usually by the sun) and vibrate quicker, becoming less dense and rise.

condensation occurs because molecules in water vapor are cooled and therefore vibrate more slowly thus becoming more dense and eventually fall to earth.

lines of equal barometric pressure on a weather map are called: isobars : lines of equal temp on a weather map are called: isotherms.​
