Concept:

  • Vector Quantity:-  Physical quantities that have magnitude and direction and obey triangle law are called vector quantities.
  • Example: Displacement, Velocity, etc.

Additional Information 

  • The velocity of a moving object is defined as the displacement of the object in the unit time interval.
  • It is a vector quantity and its SI unit is meter/second.
  • Acceleration of an object is defined as the rate of change of velocity of the object.
  • It is a vector quantity and its SI unit is (m/s2)
  • ∴ The correct answer is 20 m/s2.
