What time is required to travel a distance of 330 km along a freeway at the following constant speeds? -(a) 53.5 km/h -(b) 57.0 km/h Compute the average speed in m/s of a runner who completes a mile in 3.88 min? A force directed 54.1° below the positive x-axis has an x component of 5.02 lb. Find its y component. A certain vector A, of magnitude 5.49 units, points in a direction 31.0° to the left of the negative y-axis....
Problem 4. Given a curve C, the vectors T(t), N(t), and B(t) form a special coordinate system (called an orthonormal reference frame) that lets us discuss velocity and acceleration of a moving object from the perspective of the object itself. (Consider, for example, looking only at the motion of an airplane to study its stability without worrying about its position relative to its starting point.) (a) Use the fact that v uT, where u(t)-|r(t)l is the speed of the particle,...

Student Name 1. A particle confined to motion along the x axis moves with constant acceleration fromx = 2.0 m to x 8.0 m during a 2.5-s time interval. The velocity of the particle at x - 8.0 m is 2.8 m/s. What is the acceleration during this time interval? 2. The polar coordinates of a point are r=5.50 m and Angle 240°. What are the Cartesian coordinates of this point? 3. On occasion, the notation A= [A, O] will...
