A car moves along a straight street. The car’s initial position at time t1 is given by a position vector x! . The car’s later position vector is x2! at time t2. Suppose x1! = 700 miˆ . and x2! =400miˆ. a. If t2 – t1 = 3.0 seconds, what is the car’s average speed (assuming the car only moved in one direction)? b. What was the car’s average velocity?
A particle at t1 = -2.0 s is at x1 = 5.0 cm and at t2 = 5.0 s is at x2 = 8.9 cm . What is its average velocity over this time interval? Can you calculate its average speed from these data?
The position of a particle is described by the function x = 3.0 t2 + 5.0 t + 3.0 (m). Determine the average velocity (in m / s) for the time interval t1 = 2.0 s and t2 = 4.0 s.
Below is a motion diagram for an object that moves along a linear path. The dots represent the position of the object at three subsequent instants, t1, t2, and t3. The vectors v⃗ 21 and v⃗ 32 show the average velocity of the object for the initial time interval, Δt21=t2−t1, and the final time interval, Δt32=t3−t2, respectively. Draw the vector −v→21 and the acceleration vector a⃗ representing the change in average velocity of the object during the total time interval...
8. A student rolls a marble alongside a meterstick to measure its velocity. At t1 = -2.5 s, its position is x1 = 4.3 cm, and at t2 = 4.5 s it is at x2 = 18.5 cm. Determine its average velocity during this time interval. 9. The position of a ball rolling along a straight line is given by ? = 1.8−3.6? +1.5?2, where x is in meters and t is in seconds. Determine the average velocity of the...
An object undergoes uniformly accelerated motion from point x1 = 6 m at time t1 = 3 s to point x2 = 46 m at time t2 = 8 s. (The direction of motion of the object does not change.) (a) If the magnitude of the instantaneous velocity at t1 is v1 = 2 m/s, what is the instantaneous velocity v2 at time t2?
