Can you put it in english

Here is the solution for question 2 in English:

a) Velocity is the rate of change of an object's displacement per unit of time. It is a vector quantity, possessing both magnitude and direction. Its SI unit is meters per second ($\text{m/s}$).

b)

(i) The force acting between the box and the road is the force of friction.

(ii) This force can be reduced by making the surfaces smoother or by applying a lubricant.

c) The net force acting on the box is zero.
Explanation: Since the box is moving at a constant velocity, its acceleration is zero. According to Newton's second law ($\sum F = ma$), if the acceleration ($a$) is 0, then the sum of the forces ($\sum F$) acting on the box must also be 0.
