one or more of the could be true in special cases, they are not always true. QUESTION 8 A tumtable has a nestment A 0.600-kg ball of putty is dropped vertically on the turntable and sticks at a point 0.100 m from the center By what factor does the angular momenturm of the system change after the putty is dropped onto the turntable? of inerta of 3.00 10 2 kg m2 and spms freely on a frictionless beanng at 25.0 revimn a1.00 (no change) D b.0.820 0 d. 1.22 QUESTION 9 A 7.50-kg bowling ball strikes a S.20-kg pin. The pin flies forward with a velocity of 4.00 m/s; the ball continues forward at 5 50 ms. What was the original velocity of the ball? o a 0.128ms b. 4.61 ms m s d, 1.34 ms e. 11.3 m/s QUESTION 10 Alex throws a 0.250-kg rubber ball down onto the floor. The ball's speed just before impact is 5.30 ms, and just after is 3.71 m/s. If the ball is in contact with the floor for 0.028 s, what is the magnitude of the average force applied by the floor on the ball? a 225 N

Explanation / Answer

8. for turnable and putty system,

there will be no external torque hence angular momentum will be conserved.

Li = Lf

Ans: (a) 1

9. Applying momentum conservation,

pi = pf

(7.50 x v) + (5.20 x 0) = (5.20 x 4) + (7.50 x 5.50)

v = 8.27 m/s

Ans(c)
