The angular displacement of the centrifuge is given by e = 4.2[t + 37e 0.017t - 37] rad, where t is in seconds and t = 0 is the startup time. If the person loses consciousness at an acceleration level of 9.1g, determine the time t at which this would occur. Verify that the tangential acceleration is negligible as the normal acceleration approaches 9.1g. 32.2' Answer: t = i sec
The two cars collide at right angles in the intersection of two icy roads. Car A has a mass of 1040 kg and car B has a mass of 1005 kg. The cars become entangled and move off together witha common velocity in the direction indicated. If car A was traveling 44 km/h at the instant of impact, compute the corresponding velocity of car B just before impact. 25 B. A = 44 km/h Answer: VB = i km/h

Problem 2 A project by some to monitor the traffc safety at a busy intersection. They measwre (with a precision stopwatch) that exactly three seconds after car B passes through the intersection traveling south at vg = 55 mph, minivan A passes through at va = 70 mph on the road that runs at an angle 0 = 60° east of north. The speed of each automobile is Civil Engineering students requires them constant. Determine (a) the relative velocity (in mph) of B with respect to A, draw the vector triangles as part of your answer (b) the change in position (in fi) of B with respect to A during a 10-s interval, (c) the distance (in ft) between the two automobiles 3 s after A has passed through the intersection.
