A car starts from rest and travels for 9.0 s with a uniform acceleration of +2.4 m/s^2.The driver then applies the brakes, causing a uniform acceleration of -2.5 m/s^2. If the brakes applied for 2.0 s, determine each of the following. (a) How fast is the car going at the end of the braking period?
m/s
(b) How far has the car gone?
m

if the thermos has a vacuum innner, then heat through conv currents and conduction are reduced = vacuum flask

the five characteristics of adolescence are biological growth and development, and undefined status, increased decision making, increased pressure and the search of self.

  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.
