Not really as acceleration is rate of change of velocity therefore zero acceleration would Mean that the velocity is constant
The first one is right switch the second and third one and keep the last one and that should be right
Answer:
C = - 1.625 i + 6.06 j
Explanation:
Positive angles are measured counterclockwise.
Positive angles are measured counterclockwise. To determine the component on the x axis we use the cosine of the angle while to determine the component on the y axis we use the sine of the angle.

C = - 1.625 i + 6.06 j
Friction accord while the ball was rolling in the grass and slowed it down until it finally came to a stop
1) Equivalent resistance, 1/R = 1/15 + 1/40 + 1/60 = 8+3+2 /120 = 13/120
R = 120/13 = 9.23
2) Current, I = V/R = 115/9.23 = 12.45 A
