Chapter 11.2, Problem 11.43P

Two automobiles A and B are approaching each other in adjacent highway lanes. At t = 0, A and B are 3200 ft apart, their speeds are v_A = 65 mi/h and v_B = 40 mi/h, and they are at points P and Q, respectively. Knowing that A passes point Q 40 s after B was there and that B passes point P 42 s after A was there, determine (a) the uniform accelerations of A and B, (b) when the vehicles pass each other, (c) the speed of B at that time.

Knowing that car A passes point Q 38 s after B was there and that B passes point P 42 s after A was there. Determined: *. a) The uniform acceleration of A B -0.8 إجابتك Q4-b)the uniform acceleration of ,B

A motorist starts from rest at point A on a circular entrance ramp when t=0, increases the speed of her automobile at a constant rate and enters the highway at point B. Knowing that her speed continues to increase at the same rate until it reaches 62.5 mph at point C, determine themagnitude of the normal acceleration (ft/s2) at t=10s.

The collar P slides outward at a constant relative speed u along rod AB, which rotates counterclockwise with a constant angular velocity of 18 rpm. Knowing that r= 250 mm when e = 0 and that the collar reaches B when e = 90°, determine the magnitude of the acceleration of the collar Pjust as it reaches B. В 500 mm The magnitude of the acceleration of the collar Pjust as it reaches Bis m/s2.
