- please solve as symbolically as possiblearrow_forwardplease double check your answerarrow_forwardQ3 A car A is travelling along a straight path, while a lorry B is travelling along a circular path having a radius of curvature of 200 m as shown in Figure Q3. At the instant shown, car A travel at the velocity of (156) km/h while lorry B travel at the velocity of 80 km/h. Also at this instant, car A has an increase velocity of 7000 km/h? and lorry B has a decrease velocity of 4500 km/h?. The angle between straight path of car A and the horizontal line is 0=65°. (a) Calculate the magnitude and direction of velocity of lorry B with respect to car A. (b) Determine the magnitude and direction of acceleration of lorry B as measured by the driver of car A. A vr (150+ X)km/h vg- 80 km/h a = 7000 km/ h? B ag = 4500 km/ h² | Figure Q3arrow_forward
- Car A is traveling at the constant speed of 45 km/h as it rounds the circular curve of radius r = 380 m and at the instant represented is at the position 0 = 40°. Car B is traveling at the constant speed of 54 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 with the pole moving with B. For this instant determine VA/B and the values of r and as measured by an observer in car B. Answers: VA/B = r = 0 = i i 8 m/s m/s rad/s Barrow_forwardAt the instant shown, cars A and B are travelling at the speeds shown. If B is accelerating at 1200 mi/h2 while A maintains a constant speed, determine the magnitude of the velocity and acceleration of B with respect to A. Car B moves along the curve having a radius of curvature of 0.7mi. show all the steps in the solution pleasearrow_forwardThe arm of the robot moves so that r = 1 m is constant, and its grip A moves along the path z = (sin θ) m, where θ is in radians. If θ = πt/8 rad, where t is in seconds, determine the magnitudes of the grip’s velocity and acceleration when t = 4s.arrow_forward
