Due to slipping, points A and B on the rim of the disk have the velocities vA = 4.2 ft/s and vB = 8.4 ft/s. Determine the velocity of the center point C and point D at this instant.
A train is moving horizontally to the right with the speed of VT=60 mi/h. Meanwhile, a car is traveling toward the train with the speed of VC=30 mi/h and a 30deg angle with respect to horizontal direction. Select the correct expression of the velocity vector of the train relative to the car ___________mi/h                                A. (60-30cos30°)-30sin30°   B. (60-30cos30°) +30sin30°    C. (60+30cos30°)-30sin30°    D. (30cos30°-60)  +30sin30°
When θ = 15°, the car has a speed of 50 m/s which is increasing at 6 m/s^2. Determine the angular velocity of the camera tracking the car at this instant.
