t 0 is defined by the relation and t in seconds. Collar B slides ce from O is r 0.9 – 0.12. econds. After the arm OA has al velocity of the collar, (b) the re acceleration of the collar with %3D

A some instant in time a rocket experiences an acceleration due to gravity and thrust from the rocket engine of: and has a velocity of: ā= 5.657î -3.843ĵ m/s² v = 5000 + 2000 m/s. Determine: i) the acceleration due to the rocket engine; ii) a, and an; iii) the radius of curvature of the trajectory at this instant ANS. at = 3.825 m/s^2, an = 5.669 m/s^2, p=5,115,541 m

car A round with curve 150m radius with constant velocity 20m/s. at instant car B moving with a velocity of 30m/s and slows down 5m/s^2. find magnitude of velocity as well as acceleration of car B observed from A (Vb/a and aB/A) please show clear work
