A student standing on a knoll throws a snowball horizontally 4.5 meters above the level ground toward a smokestack 15 meters away. The snowball hits the smokestack 0.65 second after being released. [Neglect air resistance. ] 15 m Smokestack Knoll 14 4.5 m Level ground At the instant the snowball is released, the horizontal component of its velocity is approximately A) 6.9 m/s B) 9.8 m/s C) 17 m/s D) 23 m/s Base your answers to questions 28 and 29 on 30. The graph below represents the relationship between the information and diagram below. speed and time for a car moving in a straight line. Speed vs. Time A child kicks a ball with an initial velocity of 8.5 30. meters per second at an angle of 35 with the horizontal, as shown. The ball has an initial vertical velocity of 4.9 meters per second and a total time of flight of 1.0 second. [Neglect air resistance.] 20. Speed (m/s) Viy = 4.9 m/s 10.

The horizontal component of the ball's initial The magnitude of the car's acceleration is velocity is approximately A) 1.0 m/s B) 0.10 m/s A) 3.6 m/s B) 7.0 m/s C) 10 m/s2 D) 0.0 m/s2 C) 4.9 m/s 0) 13 m/s 29. The maximum height reached by the ball is approximately A) 1.2 m B) 2.5 m C) 4.9 m D) 8.5 m Base your answers to questions 31 through 34 on the | 35. Note that the question below only has three following information. In the diagram below, a choices. 10.-kilogram sphere, A, is projected horizontally with a velocity of 30. meters per second due east from a height of 20. meters above level ground. At the same instant, a 20.-kilogram sphere, B, is projected The diagram below represents the path of a stunt car horizontally with a velocity of 10. meters per second that is driven off a cliff, neglecting friction due west from a height of 80. meters above level A Path of car ground. [Neglect air friction. ] v - 10. m's west B 20-kg sphere A V= 30. m/'s east 10. m 20. m 10.-kg sphere Compared to the horizontal component of the car's 20. m velocity at point A, the horizontal component of the 100. m car's velocity at point B is A) smalle B) greater 31. Initially, the spheres are separated by a horizontal ") the same distance of 100. meters. What is the horizontal 36. Two spheres, A and B, are simultaneously projected separation of the spheres at the end of 1.5 seconds? horizontally from the top of a tower. Sphere A has a A) 15 m B) 30 m horizontal speed of 40. meters per second and sphere C) 40. m D) 45 m 3 has a horizontal speed of 20. meters per second. Which statement best describes the time required for 32. Compared to the vertical acceleration of sphere A, the spheres to reach the ground and the horizontal the vertical acceleration of sphere B is distance they travel? [Neglect friction and assume A) the same B) twice as great the ground is level. ] C) one-half as great D) four times as great A) Both spheres hit the ground at the same time 33. The magnitude of the horizontal acceleration of and at the same distance from the base of the sphere A is tower. A) 0.0 m/s2 B) 2.0 m/s2 B) Both spheres hit the ground at the same time, but sphere A lands twice as far as C) 9.8 m/s2 D) 15 m/s sphere B from the base of the tower. 34. Initially, the spheres are separated by a horizontal C) Both spheres hit the ground at the same time, distance of 100. meters. What is the horizontal but sphere B lands twice as far as sphere A separation of the spheres at the end of 1.5 seconds? rom the base of the tower. A) 15 m B) 30 m D) Sphere A hits the ground before sphere B, and C) 40. m D) 45 m sphere A lands twice as far as sphere B from the base of the tower
