(c) In your hand. (d) Can't decide from the given information. l saight up km/h.I 10. A hunter is aiming horizontally at a monkey who is sit falls down while the bullet speeds straight forward (b) The bullet will hit the monkey because both the 8. Which of the three kicks in Fig. 3-32 is in the air for the longest time? They all reach the same maximum height h. Ignore air resistance. (a), (b). (c), or (d) all the same time monkey and the bullet are falling downward at the same rate due to gravity (c) The bullet will miss the monkey because although both the monkey and the bullet are falling downward due to gravity, the monkey is falling faster. (d) It depends on how far the hunter is from the monkey 11. Which statements are not valid for a projectile? Take up a positive. (a) The projectile has the same a velocity at any point on its path. (b) The acceleration of the projectile is positive and decreasing when the projectile is moving upwards, zero at the top, and increasingly negative as the projectile descends. (c) The acceleration of the projectile is a constant negative value. (d) The y component of the velocity of the projectile is FIGURE 3-32 MisConceptual Question 8. zero at the highest point of the projectile's path. (e) The velocity at the highest point is zero. 9. A baseball is hit high and far. Which of the following state- ments is true? At the highest point, (a) the magnitude of the acceleration is zero. (b) the magnitude of the velocity is zero. (c) the magnitude of the velocity is the slowest. (d) more than one of the above is true. (e) none of the above are true. 12. A car travels 10 m/s east. Another car travels 10 m/s nor The relative speed of the first car with respect to the secon (a) less than 20 m/s. (b) exactly 20 m/s. (c) more than 20 m/s.Explanation / Answer
7. C) in your hand
relative horizontal velocity between you and baseball is zero
8. d) all the same time
all have same maximum height and they will take same time
9. c) the magnitude of velocity is slowest
at heighest point velocity is slowest and acceleration is equal to gravitational acceleration
10. b) the bullet will hit the monkey
