I believe its vibration or my teacher taught me wrong
Answer:
The tension in the tow rope pulling the log is 784.61 N
Explanation:
Given:
v = speed = 13 m/s
Pf = final power when the log is pulled = 8.5x10⁴W
Pi = average power = 7.48x10⁴W
The force required to move a car is equal to:
T = Ff - Fi = 6538.46 - 5753.85 = 784.61 N
I'm preeeety sure the answer is A, lost! Hope I helped, hon :)
C, 184,000 KM, as it means, "Kilometers", is a measurement of distance, close to miles.
