(a) Give two examples each of:

(i) rotational motion;

(ii) linear motion.

(b) Describe a laboratory experiment to determine the density of an irregularly shaped solid.

(c) State Newton's second law of motion

(d) Explain the term inertia.

(e) 

The diagram above illustrates a body of mass 5.0 kg being pulled by a horizontal force F. If the body accelerates at 2.0 ms\(^{-2}\) and experiences a frictional force of 5 N, calculate the:

(i) net force on it;

(ii) magnitude of F;

(iii) coefficient of kinetic friction. [ g = 10 ms\(^{-2}\)]
