1.11 The position coordinate x of a particle is determined by its velocity v and the elapsed time t as follows: (a) x = At² – Bvt; and (b) x = the dimensions of constants A and B in each case, assuming the expressions to be dimensionally correct. Avte-B. Determine

At 9:13 A.M., a sports car is traveling 30 miles per hour. Two minutes later, the car is traveling 90 miles per hour. The mean value theorem guarantees that at some time during this two-minute interval, the car's acceleration is exactly A miles per hour squared. Compute the value of A. A = mi/h² Need Help? Read It

(a) Suppose that the displacement of an object is related to time according to the expression x = Bt2. What are the dimensions of B? O L²/L T OLX T² O T²/L OL/T O L/T² (b) A displacement is related to time as x = A sin(2πft), where A and fare constants. Find the dimensions of A. (Hint: A trigonometric function appearing in an equation must be dimensionless.) OL/T OLX T O T/L OL T
