Question
D. B. 2.427 cm/s 3.679 cm/s 7. A particle is displaced from the point x 3.264 cm to the point x 15.822 cm. And then it is displaced back to the point 10.943 cm Determine its displacement and the distance it travelled respectively ( point) A 7.679 cm, 17.437 cm B. 11.698 cm, 1.841 cm C. 7.679 cm, 12.086 cm D. 9.929 cm, 12.086 cm E 9.929 cm, 17.437 cm 8. A particle is displaced from the point x-9 cm to the point x Calculate its average velocity and its average speed respectively. (1 point) 13 cm in 5 seconds. And then it is displaced back to the point 8 cm in,33 seconds A. -0.077 cm / s, 1.794 cm / s B. -0.077 cm/s, 1.08 cm/s C..0.12 cm / s, l.794 cm, s D. -0.12 cm/s, 1.08 cm/s E. -0.103 em s, 0.362 cm's 9. The following is the graph of position versus time for a certain particle.Explanation / Answer
7)
a)
displacement = final x - initial x
= 10.943 cm - 3.264 cm
= 7.679 cm
b)
Distance is always positive
distance1 = |15.822 - 3.264|
= 12.558 cm
distance2 = |10.943 - 15.822 |
= 4.879 cm
total distance = 12.558 cm + 4.879 cm
= 17.437 cm
