QUESTION 17 Shown below are the velocity and acceleration vectors for an object in several different types of motion. In which case is the object slowing down and turning to its right? DB.

1. A particle moves on a vertical line so that its coordinate at time t is y= 213 - 16t+3, t 2 0. (a)Graph the position, velocity, and acceleration functions for 0 sts 3. (b)When is the particle speeding up? When is it slowing down?

A particle travels along the +x axis. At t = 0 s, its velocity is 10.0 m/s and its acceleration is -2.0 m/s^2.  Question A: Which of the following statements is true?           1. The particle will slow down and eventually come to a complete stop           2. The particle cannot have a negative acceleration and be moving in the positive x direction           3. The particle will continue to move in the positive x direction, slowing but never coming to a complete stop.           4. The particle will slow down, stop momentarily, then speed up in the x- direction.  Question B: At what time will the particle be stopped?           1. t = 5.0 s          2. t = -5.0 s          3. t = -0.2 s          4. The particle does not ever stop  Question C: What is the particle's displacement from its initial position at t = 10.0 s ?  Please Answer questions A, B, and C

Light travels at a constant speed of 3.00 x 10^8 m/s, whereas sound travels through the air at a constant speed of 343 m/s A. How long does it take for light to travel from a lightning stroke to an observer 12.9 km away? B. For the observer, how long after the flash is seen is the thunder heard?
