1.A truck passed a red light at a speed of 20 m/s and started accelerating at 0.15 m/s/s. A police car 30 m behind the truck started from rest with acceleration 0.6 m/s/s to pursuit the truck. Find the distance from the traffic light when the police caught up with the truck. Plot the position versus time information for the police car and truck on the same graph. Find the truck acceleration if the catch-up distance is double.(adsbygoogle = window.adsbygoogle || []).push({});

2.Given the following 2-block friction system, does the system move? Show calculation

If it moves, calculate the tension and the acceleration.

a=2 kg, b=10 kg, u=.25, angle=30 degrees. find the acceleration and tension

T-(2)(9.8) sin30 - (0.25)(2)(9.8) cos30 = 2a
