Question

A particle is moving at a constant speed in a
circular trajectory centered at the origin of an xy
co-ordinate system. At one point (x=4m, y=0m) the
particle has a velocity -5.0 j m/s. Determine
acceleration of particle.

Displacement Calculation:

• Displacement is outlined as the change available of an object. It is a heading size and has a management and size. It is presented as an missile that points from the offset position to the ending position. For example- If an object moves from A position to B, before the object’s position changes. This change available of an object is famous as Displacement.

• Distance and dislocation are two quantities that appear to mean the alike but are clearly various accompanying various significations and definitions. Distance is the measure of “by what method much ground an object has enclosed all the while allure motion” while dislocation refers to the measure of “by virtue of what unusual of place is an object.” In this item, allow us believe the distinctness 'tween distance and dislocation.
