Problem 2Figure 2-15 gives the acceleration a(t) of a Chihuahua as it chases a German shepherd along anaxis. In which of the time periods indicated does the Chihuahua move at constant speed Step-by-step solutionConcepts and reasonThe 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 accelerationvs time plot.FundamentalsAcceleration is the rate of change of velocity with time.Expression for acceleration is, dva = dtHere, a is the acceleration.If the velocity is constant, the above expression gives that, dv = 0 dtHence the acceleration of constant speed motion is zero.Step 1 of 2Chihuahua chases a German shepherd along the x axis.Its velocity is expressed as, dzv = dtAcceleration of Chihuahua is expressed as,a = dv dtAcceleration of motion is the rate of change of velocity with respect to time and hence it ispointed
