9. If the ball is thrown up, the clocity a. b. c. is increasing is decreasing stays the same 10. If the ball is dropped from a certain height, the yclocity b. c is decreasing stays the same 11. If the ball is thrown up, the acceleration is increasing a. b. is decreasing c. stays the same 12. If the ball is dropped from a certain height, the accelcration a. iS incrcasing b. is decreasing c. stays the same 13. If a ball is traveling with a speed of 10 m/sec horizontally, what is its final horizontal speed before it hits the ground? Friction force due to air is ignored. 14. 2.2 m 15. 310 cm- 16. (100)° (X) (z) 17 18, Solve for the angle , when tan (0)-0.24 19. In the equation for density -mV, where m is the mass and V is the volume, which of the cm 20x10x30 0 following statements is true? a. b. c. d. 20. 1 gm/cm Density is directly proportional to m and inversely proportional to V Density is inversely proportional to m and directly proportional to V Density does not depend either on mass or volume Density increases when the volume increases.Explanation / Answer
(9) If the ball is thrown up, its velocity keeps decreasing
(10) If the ball is thrown down, its velocity keeps increasing.
(11) If the ball is thrown up, the acceleration remains constant.
(12) If the ball is thrown down, the acceleration remains constant.
