acceleration of a particle moving horizontally under rectilinear motion is defined by the relation  a=8.9t2-5.1t where a is in ft/s2 and t is in s. Initially, the particle is at rest and started at x=14.3 ft. Determine the position of the particle at t=4.3s. Round off only on the final answer expressed in 3 decimals. Indicate appropriate units.

Conservation of Energy

In physics, the rule of the conservation of energy states that energy doesn’t disappear from the atmosphere; instead, it changes its form from one type to another. Energy is one of the most important physical quantities in nature, and it cannot be created or destroyed — only transformed.
