Solution

Dear Student,
(a) The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object

mathematicaly,
F=ma

(b) Therefore SI unit of force from the above expression is......
F= kg m/s²
(c) F=m.a so m=F/a=525/3.5=150kg
