The Displacement D (In Meters) of an Object at Time $$d = - 2 \sin ( 5 t )$$

question 68

Multiple Choice

The displacement d (in meters) of an object at time t (in seconds) is given. Describe the motion of the object. What is the
maximum displacement from its resting position, the time required for one oscillation, and the frequency?
- $$d = - 2 \sin ( 5 t )$$

Graph

A diagram showing the relation between variable quantities, typically of two variables measured along a pair of lines at right angles.

Reactants

Materials that exist before a chemical reaction starts and are used up to create end products during the reaction.

Hydrogen Ion Acceptor

A hydrogen ion acceptor, often a base in chemical terms, is a compound that is capable of accepting a hydrogen ion (H+) from another compound, thus participating in neutralization or buffer reactions.
