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.

Employer informs its employees that it will hold a substantial cash prize drawing for each work group at the end of each month in which no employee in the work group sustains a lost-time injury. tyra reports an injury that she sustained while operating a mechanical power press. tyra did not violate any employer safety rules when she sustained her injury. tyra’s injury requires her to miss work for two days. her employer cancels the cash prize drawing for that month for tyra’s work group because of tyra’s lost-time injury. did the employer misuse an incentive program to retaliate against tyra?
