The velocity is 4374.45 m/s.
I got the answer by using v=d/t.
20,000meters / 25min= 4,374.45 m/s.
Answer: 1
Explanation: The highest eccentricity an ellipse can have is '1', a straight line.
Answer:-600N
Explanation:
Mass(m)=1000kg
Initial velocity(u)=25m/s
Final velocity(v)=12.5m/s
Time(t)=22 seconds
v=u+axt
12.5=25+ax22
collect like terms
12.5-25=22a
-12.5=22a
Divide both sides by 22
-12.5/22=22a/22
-0.6=a
Acceleration=-0.6
Force=mass x acceleration
Force=1000 x -0.6
Force=-600
A. they are both a renewable energy
