Calculate the center of mass of 4 objects having masses of 18 kg, 5 kg, 8 kg and 22 kg which are located along the x-axis at positions xi-0.6 m, x2--0.2 m, xy- 0.5 m and x41.2 m, respectively. a 0.17 kg cue ball strikes the rail of a pool table at a speed of 8 m/s, rebounding with a velocity of 6 m/s. a) calculate the impulse delivered to the ball by the pool table. b) what average force would produce this impulse, if the total time duration of the impact is 20 msec? (1 msec 1 millisecond- 0.001 sec) 10. 1. the equation of motion describing the angular position of a spinning wheel is given by the expression o(t)-12t-3t (rad]. what is the total angular displacement in degrees from t-4 sec to t-6 sec?
