The diagram shows a movement of a car in \(3 \) seconds.
The car is moving with \(\underline {\hspace {3.5cm}}\).
A boy rides his bike for \(2 \space \text {km}\) from his house to a shop. After that, he comes home. On the way home, he stops at a stall just \(1.2 \space \text {km}\) from his home.
What is the distance and displacement the boy travels from home to stall?
Distance (\(\textbf {km}\))
Displacement (\(\textbf {km}\))
(A)
\(2.8 \)
\(0.8\)
(B)
\(1.2 \)
(C)
\(3.2 \)
(D)
\(0.8 \)
Hisham starts driving his car from the house with uniform acceleration and reaches the speed of \(15.00 \space \text m \text s^{-1}\) in \(5 \) seconds.
What is the acceleration and the displacement of the car as soon as the car starts moving?
A speeding car with a velocity of \(40 \space \text m \text s^{-1}\) was stopped shortly after the brake was pressed. The distance traveled by car before stopping is \(100 \space \text m\).
Calculate the deceleration of the car?
(A) \(1 \space \text m \text s^{-2}\)
(B) \(8 \space \text m \text s^{-2}\)
(C) \(-1 \space \text m \text s^{-2}\)
(D) \(-8 \space \text m \text s^{-2}\)
A policeman sees a thief towards a junction with a uniform velocity of \(0.6 \space \text m \text s^{-1}\). At that time, the position of the policeman, the thief and the junction are shown in the diagram respectively.
If the policeman runs towards the thief with a uniform acceleration of \(1.5 \space \text m \text s^{-2}\), can the policeman catch the thief before he reaches the junction?
There is something wrong with this question.
