A car decelerates uniformly from $54 \mathrm{km}/\mathrm{h}$ to rest after travelling a distance of $20 \mathrm{metres}$. Find the acceleration of the car.

Three particles A, B and C are thrown from top of a building with same speed. A is thrown upwards, B is thrown downwards and C is thrown horizontally, they hit the ground with speed $V_A$, $V_{B }$and $V_C$ respectively then

A particle starts its motion from rest under the action of a constant force. If the distance covered in first 10 seconds is S1 and that covered in next 10 seconds is S2 then

The velocity – time graph of a moving body is shown in the figure. Which of the following statements is true?

A body is projected vertically upward direction with a speed $u$. Find the (a) time taken (b) distance travelled by the body in reaching its topmost point.
