1) a particle moves in a circular path at constant speed. the initial location of the particle is (5.47m,6.09m) at t=3.29 s. the velocity of the particle at this time is 3.07m/s j (i. e., directed along the positive y-axis). acceleration at this time is along the +x axis. at t=9.29 s, v is -3.07m/s i and the acceleration is directed along the +y axis. find the radius of the circle (in meters). assume that the time interval is less than 1 period.
2) a particle moves in a circular path at constant speed. the initial location of the particle is (4.51m,5.87m) at t=4.2 s. the velocity of the particle at this time is 2.99m/s j (i. e., directed along the positive y-axis). acceleration at this time is along the +x axis. at t=9.27 s, v is -2.99m/s i and the acceleration is directed along the +y axis. find the x-coordinate of the center of the circle (in meters). assume the time interval is less than 1 period.

(a) assume the equation x = at^3 + bt describes the motion of a particular object, with x having the dimension of length and t having the dimension of time. determine the dimensions of the constants a and b. (use the following as necessary: l and t, where l is the unit of length and t is the unit of time.) (b) determine the dimensions of the derivative dx/dt = 3at^2 + b. (use the following as necessary: l and t, where l is the unit of length and t is the unit of time.)
