During the formation of our solar system, the nebular dust began to cool and sections began to condense. Eventually, small grains stuck to one another via an electromagnetic force. As they grew, gravity helped to speed up the building process until planetesimals were formed. This process is called A) accretion.
B) expansion
C) orderly motion
D) angular momentum

Answer: it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.explanation:   we have equation of motion ,where s is the displacement, a is the acceleration, u is the initial velocity and t is the time taken.average velocity = displacement/ time taken.average velocity = 10.69 miles/hr = 10.69*1.6*1000/(60*60) = 4.75 m/s4.75 = s/ts = 4. 1we also have acceleration = 2.18 m/s², initial velocity = 0 m/sso it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.
