Question:

For the cars of Prob. 2 /195, determine the instantaneous values of r¨ and θ¨ if car A is slowing down at a rate of 1.25 m/s² and car B is speeding up at a rate of 2.5 m/s². Refer to the printed answers for Prob. 2/195 as needed.

Data from Prob. 2/195

At the instant illustrated, car B has a speed of 30 km/h and car A has a speed of 40 km/h. Determine the values of r˙ and θ˙ for this instant where r and θ are measured relative to a longitudinal axis fixed to car B as indicated in the figure.
