,1. A particle A has mass 4m and a particle B has mass 3m. The particles are moving along
the same straight line on a smooth horizontal table. The particles are moving in opposite
directions towards each other when they collide directly.

As a result of the collision, the direction of motion of each particle is reversed.

Immediately before the collision, the speed of A is u and the speed of B is ku, where k
is a constant.
Immediately after the collision, the speed of A is 2v and the speed of B is 3v.
The magnitude of the impulse received by A in the collision is 20mv.

(a) Find u in terms of v only.
(3)
(b) Find the exact value of k.

modelled as a force of magnitude 50v N.

The engine of the van is working at a constant rate of 12 kW.

At the instant when the speed of the van is V ms1, the acceleration of the van
is 0.2 ms2
Using the model,

(a) find the value of V.

Later on, the van is moving up a straight road that is inclined at an angle α to the
1
horizontal, where sin α  . When the speed of the van is v ms1, the resistance

to the motion of the van from non-gravitational forces is modelled as a force of
magnitude 50v N.

When the van has constant speed U ms−1, the engine of the van is working at a constant
