It moves backwards do to the impact. this is because force can not be created nor destroyed so it is transferred.<span />
First, we have a change in the velocity from 85 to 164 m/s in 10 sec.
Then, we calculate the <u>acceleration </u>as:

Hence we need to calculate the velocity of the space vehicle at t = 2 sec using the first equation of motion:

Then, using the second equation of motion to calculate the distance:


I do not recall the answer to this question
Because the air in their wings helps them fly
The answer is true. Gravity is the force that keeps us all on the ground.
