	Distance (\(\textbf {km}\))	Displacement (\(\textbf {km}\))
(A)	\(2.8 \)	\(0.8\)
(B)	\(2.8 \)	\(1.2 \)
(C)	\(3.2 \)	\(1.2 \)
(D)	\(3.2 \)	\(0.8 \)

Report 3 / 5

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?

	Acceleration	Displacement
(A)	\(2.00 \space \text m \text s^{-1}\)	\(27.50 \space \text m\)
(B)	\(3.00 \space \text m \text s^{-1}\)	\(27.50 \space \text m\)
(C)	\(2.00 \space \text m \text s^{-2}\)	\(37.50 \space \text m\)
(D)	\(3.00 \space \text m \text s^{-2}\)	\(37.50 \space \text m\)

Report 4 / 5

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) \(8 \space \text m \text s^{-2}\)

(D) \(-8 \space \text m \text s^{-2}\)

2.1 Linear Motion - Set 1

Report 5 / 5

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?
