The car is modelled as a particle.
(a) Use the model to find the speed of the car 4 s after passing the signpost.

Figure 1 below shows the horizontal forces acting on the car.
Given that
• the car has mass 800 kg
• the driving force of the engine has magnitude D newtons
• the resistance to the motion of the car has magnitude 400 N
• the acceleration of the car is 2 ms–2 in the direction of the driving force
(b) use the model to find the value of D.

A small box B of mass 2 kg is dragged in a straight line, along a rough horizontal plane,
at a constant speed by a force of magnitude 5 N.

At the instant when B is at the point O on the plane, the force of magnitude 5 N
is removed.

(c) Find the magnitude of the normal reaction of the plane on the box after the force of
magnitude 5 N is removed.
(1)
Given that after the force of magnitude 5 N is removed
• the box is modelled as a particle
• air resistance is modelled as being negligible
• the coefficient of friction between the box and the plane is modelled as 0.2
• the speed of the box as it passes through O is 4 m s–1
• the box comes to rest at the point X on the plane
(d) use the model to find the length OX.
