Question
what is the answer for part C?
In your physics lab, a block of mass m is at rest on a horizontal surface. You attach a light cord to the block and apply a horizontal force to the free end of the cord. You find that the block remains at rest until the tension T in the cord exceeds 20.0 N. For T > 20.0 N, you measure the acceleration of the block when T is maintained at a constant value, and you plot the results (Figure 1). The equation for the straight line that best fits your data is a = [0.182m/(N s^2)]T - 2.842m/s^2. For this block and surface, what is the coefficient of kinetic friction. Meu_k = 0.290 If the experiment were done on the earth's moon, where g is much smaller than on the earth, would the graph of a versus T still be fit well by a straight line? If so, how would the slope and intercept of the line differ from the values in the plot? The slope (1/m) would be greater, and the intercept (meu_kg) would be less negative. The slope (1/m) would be smaller, and the intercept (meu_kg) would be more negative. The slope (1/m) would be the same, but the intercept (meu_kg) would be less negative. The slope (1/m) would be the same, but the intercept (meu_kg) would be more negative.Explanation / Answer
if the experiment is done on earths moon the acceleration due to gravity will be (1 / 6) that of the earth so that the friction reduces to (1 / 6) of the actaul value
the opition will be
"the slope(1 / m) would be the same but the intercept (muk g) would be more negative"
