It was once recorded that a Jaguar left skid marks that were 320 m in length. Assuming that the Jaguar skidded to a stop with a constant acceleration of -2.2 m/s2 , determine the speed of the Jaguar before it began to skid.

The speed of the Jaguar before it began to skid : 32.532 m/s

Linear motion consists of 2: constant velocity motion with constant velocity and uniformly accelerated motion with constant acceleration  

An equation of uniformly accelerated motion  

vt = vo + at  

vt² = vo² + 2a (x-xo)  

x = distance on t  

vo / vi = initial speed  

vt / vf = speed on t / final speed  

a = acceleration  

b. latent learning (the word "latent" itself means something that exists but isn't obvious, only under certain conditions! )

  distance on the y-axis and time on the x-axis.

explanation:

the instantaneous velocity = change in position/time taken

the slope of the graph should give instantaneous velocity.

  slope of a graph = change in value of y -axis / change in values of x -axis

  comparing both the equations

    change in value of y -axis = change in position

  change in values of x -axis = time taken

so position values should be on the y axis and time values should be on the x axis.

distance on the y-axis and time on the x-axis.
