The total external force on the 10-kg object shown in the figure is given as a function of time by F = (-20t+90) i 60j + (10t+40) k (N). At time t = 0, its position is x = 20 m, y = 60 m, z=-450 m, and its velocity is v=-11li + 24j + 26k (m/s). What is its position at t = 3 s?

Submitted Answers ANSWER 1: Deduction: -3% Ft, F 6894.67, 2585.84 lb Term 1: Review your calculations and make sure you round to 3 significant figures in the last step. Constants The airplane flies with constant velocity v along a circular path in the vertical plane. The radius of the airplane's circular path is 2500 m. The mass of the pilot is 71 kg. Part A The pilot will experience "weightlessness" at the top of the circular path if the airplane exerts no net force on him at that point. Draw a free-body diagram of the pilot and use Newton's second law to determine the velocity v necessary to achieve this condition. Express your answer with the appropriate units. Figure 1 of 1 v = 157 Submit Previous Answers Part B Correct Suppose that you don't want the force exerted on the pilot by the airplane at the top of the path to exceed five times his weight. If he performs this maneuver at v = 200 m/s, what is the minimum acceptable radius of the circular path? (Figure 1) Express your answer with the appropriate units.

Incorrect; Try Again; 2 attempts remaining As shown, a cam has a shape that is described by the function r=ro (2.00- cos 0), where ro = 1.36 m A slotted bar is attached to the origin and rotates in the horizontal plane with a constant angular velocity of 0.605 radians/s. The bar moves a roller having a mass of 16.9 kg along the cam's perimeter. A spring holds the roller in place; the spring's spring constant is 19.2 N/m. The friction in the system is negligible. When = 165, what are F, and Fe, the magnitudes of the cylindrical components of the total force acting on the roller?
