I am having trouble with an average speed problem. The problem states that a person walks at 4.5 meters per second from point a to b. Then walks back from point b to a at a speed of 3.2 m/s. I know that average speed is displacement/time. However I am not sure how to calculate time or displacement from the two givens. The problem also gives that the average velocity is 0.
A particle moves along the x axis. Its x coordinate varies with time according to the
expression x = 3t° – 2t +5, where x is in meters and t is in seconds.
a) Determine the displacement of the particle in the time intervals t=1s to t=3s.
b) Calculate the average velocity in the time intervals t=1s to t=3s.
c) Find the instantaneous velocity of the particle at t=2.5s.
d) Calculate the average acceleration in the time intervals t=1s to t=3s.
e) Find the instantaneous acceleration of the particle at t=2.5s.
In this problem you will determine the average velocity of a moving object from the graph of its position x(t)x(t) as a function of time ttt. A traveling object might move at different speeds and in different directions during an interval of time, but if we ask at what constant velocity the object would have to travel to achieve the same displacement over the given time interval, that is what we call the object's average velocity. We will use the notation vave[t1,t2]vave[t1,t2] to indicate average velocity over the time interval from t1 to t2. For instance, vave[1,3]vave[1,3] is the average velocity over the time interval from t=1 to t=3.
find V(ave) [0,3]
