Analysis Plot against t. This should be a straight line with intercept v, and slope a/2. = Explain why this is so. Note that t = 0 must be included in order to obtain the y-intercept, but = = 0 need not be. You must, however, make sure that your y-intercept will lie on the graph. From the graph v, = Slope of the graph = Hence a= Discussion The slope of your graph is , whereas from equation (A2.2) the slope of a v-t graph is a. → Explain the difference. For a block sliding down down a frictionless slope the acceleration is equal to g sin 0, where is the angle that the incline makes with the horizontal, and g is the acceleration due to gravity. Measure the approximate value of @ for the rails, and calculate the value of g sin 0 (Use g = 10 m.s-2) Why is your measured acceleration of the wheel and axle completely different from Why is your measured acceleration of the wheel and axle completely different from g sin ?
