HELP ASAP!! A Cesna-182 Skylan starts at rest at one end of a runway undergoes a uniform acceleration of 9.73 m/s2 for 15.2s before takeoff. What is its velocity at takeoff?

147.896m/s.

Explanation:

initial velocity(u) = 0, since it started from rest.

acceleration (a) = 9.73m/s2

time taken (t) = 15.2s

Using the first equation of motion:

v = u + at

v = 0 + 9.73(15.2)

v = 147.896m/s

hence the velocity at the takeoff is 147.896m/s.

answer: d. a cme increases the amount of energy in the solar wind

explanation:

coronal mass ejections, also called cmes, are large clouds of plasma and magnetic field that erupt from the sun. only when the cloud is aimed at earth will the cme hit earth and therefore cause impacts. high-speed solar wind streams come from areas on the sun known as coronal holes.
