ANSWER:Problem 2
Figure 2-15 gives the acceleration a(t) of a Chihuahua as it chases a German shepherd along an axis. In which of the time periods indicated does the Chihuahua move at constant speed?
Step by Step Solution
Concepts and reason
The concept used to solve this problem is constant speed and acceleration.
Calculate the magnitude of time period of constant speed of Chihuahua by using the acceleration vs time plot.
Fundamentals
Acceleration is the rate of change of velocity with time.
Expression for acceleration is,
Here, is the acceleration.
If the velocity is constant, the above expression gives that,
Hence the acceleration of constant speed motion is zero.
Step 1 of 2
Chihuahua chases a German shepherd along the x axis.
Its velocity is expressed as,
Acceleration of Chihuahua is expressed as,
Acceleration of motion is the rate of change of velocity with respect to time and hence it is pointed
