1. While John is traveling along a straight interstate highway, he notices that the mile marker reads 260. John travels until he reaches the 150-mile marker and then retraces his path to the 175-mile marker. What is John’s displacement from the 260-mile marker?
1. A poorly tuned Geo Metro can accelerate from rest to a speed of 28 m/s in 20 s. a. What is the average acceleration of the car? b. What distance does it travel in this time? 2. At t = 0 a car has a speed of 30 m/s. At t = 6 s its speed is. 14 m/s. What is its average acceleration during this time interval? Time (s) 3.
Lastly, for motion during which acceleration changes drastically, such as a car accelerating to top speed and then braking to a stop, motion can be considered in separate parts, each of which has its own constant acceleration. Displacement and Position from Velocity. To get our first two equations, we start with the definition of average velocity:
Question 1:-The displacement (in meter) of a particle moving along x-axis is given by $x=18t+5t^2$. Calculate (i) Instantaneous velocity at $t=2s$ (ii) average velocity between $t=2s$ and $t=3s$, (iii) Instantaneous acceleration.

velocity of the rock at 4.0 s? What is the displacement of the rock at 4.0 s? 2. Suppose the tourist in question #1 instead threw the rock with an initial velocity of 8.0 m/s [down]. Determine the velocity and displacement of the rock at 4.0 s (Remember the v i is down and must become a -8.0 m/s) 3.
a. Calculate the average speed (in m/s) and the average velocity (in m/s) of the skier during the three minutes of recreation. b. Calculate the average velocity (in m/s) of the second minute (from 1 to 2 minutes).
