The displacement of a particle which moves along a straight line is given by S = 4t3 + 3t2- 10 where is in meters and t is in seconds. The time taken by the particle to acquire a velocity of 18 m/sec from rest, is

Applied mechanics is the branch of science concerned with the motion of any substance that can be experienced or perceived by humans without the help of instruments. In short, when mechanics concepts surpass being theoretical and are applied and executed, general mechanics becomes applied mechanics.

Statics is a topic under Mechanics which studies the conditions under which an object or a structure subjected to time-invariant (static) forces is in equilibrium - i.e. the conditions under which it remains stationary or moves with a constant velocity.
