For the first question, you got them right, for the two you left blank, initial(beginning) velocity: 2 m/s the final velocity is: 12 m/s
The amount of energy before and after any energy transformations remain the same because energy cannot be created or destroyed. From the law conservation of energy; any time energy is transferred between two objects, or converted from one form into another, no energy is created and none is destroyed. The total amount of energy involved in the process remains the same.
Answer:
S = V t + 1/2 a t^2 = 5 m/s * 5 s + .2 m/s^2 * 25 s^2 =
25 m + 5 m = 30 m distance traveled
Vf = V + a t = 5 m/s + .4 m/s^2 * 5 s = (5 + 2) m/s = 7 m/s final velocity
C. Their strengths are added
a. linear pairs, when added together, the angles will make 180 degrees, or a straight line. In this case No, for when you combine the two angles, it is not a straight line
b. False. Vertical angles make two opposite angles that are congruent
c. True. When added together, angles 1 and 4 make a straight line
d. False. As stated for question b, the two opposite angles must be congruent
hope this helps
