2/203 Car A is traveling at the constant speed of 60 km/h as it rounds the circular curve of 300-m radius and at the instant represented is at the position 0 = 45°. Car B is traveling at the constant speed of 80 km/h and passes the center of the circle at this same instant. Car A is located with respect to car B by polar coordinates r and 6 with the pole moving with B. For this instant determine vAB and the val- ues of i and è as measured by an observer in car B. Ans. VAB = 36.0 m/s i = -15.71 m/s, è = 0.1079 rad/s

A laser pointer, located at O, is aimed at the top of a tunnel, the shape of which is such that rAO=L(1+sinθ). The pointer is swung in a counterclockwise manner such that θ˙=(2.0 rad/s2)t. Assume that the swing began at θ=0 when t=0 s. What are υA and aA when θ=π2, where A is the point on the tunnel where the laser beam hits?

The x-coordinate of a particle in curvilinear motion is given by x= 1.7t³-5.6t where x is in feet and t is in seconds. The y-component of acceleration in feet per second squared is given by ay - 5.7t. If the particle has y-components y = 0 and v, -4.8 ft/sec when t-0, find the magnitudes of the velocity v and acceleration a when t - 3.4 sec.
