Question

(5%) Problem 3: Answer the following questions using the following table of base quantities, derived quantities and units. Use dimensional analysis to guide your thinking. Part (a) Using dimensional analysis, determine the units of the quantity ?t. Select the best answer. s Part (b) Which of the following will be a distance? Select all that apply. a?t, v?t, v/?t, 1/2 a (?t)² Part (c) Are the units of the formula v² = 2ar dimensionally consistent? Select the single answer. yes - both v² and 2ar have units of m²/s² Part (d) Are the units of the formula ma = mv²/2 dimensionally consistent? Select the best answer. no - ma has units of kg·m/s² and 1/2mv² has units of kg·m²/s² Part (e) Which of the following will have units of kg·m²/s²? Select all that apply. mar, mv, 1/2 mv² Part (f) Given the formula p = mv, what are the units of p? Units_p = j Part (g) Given the formula F = ma, what are the units of F? Part (h) Given the formula E = 1/2mv², what are the units of E?
