The brakes applied to a car produce an acceleration of $6\, m s ^{-2}$ in the opposite direction of motion. If the car takes $2\, s$ to stop after the application of the brakes, calculate the distance it travels during this time.

Which of the following figures (Fig.) represents uniform motion of a moving object correctly ?

Prove that if a body is thrown vertically upward, the time of ascent is equal to the time of descent.

What is the relationship between the distance travelled and the time elapsed for motion with uniform velocity ?

The velocity$-$time graph of a truck is plotted below

$(a)$ Calculate the magnitude of displacement of the truck in $15$ seconds.

$(b)$ During which part of the journey was the truck decelerating ?

$(c)$ Calculate the magnitude of average velocity of the truck.
