Instantaneous velocity for a displacement function d(t)= 2 - 2t at any time is given by _.

Correct answer: D. -2

  • A. -2t
  • B. 2t
  • C. 2
  • D. -2

Explanation

To find the instantaneous velocity at any time for a displacement function, you need to take the derivative of the displacement function with respect to time. In this case, the displacement function is given as d(t) = 2 - 2t. Taking the derivative of d(t) with respect to t: d'(t) = -2 The derivative of the displacement function is -2. This means that the instantaneous velocity at any time for the given displacement function is -2 units per unit of time.

About Force and Motion

Displacement, velocity and acceleration describe motion, including the horizontal and vertical components of projectile motion. The chapter connects these quantities with Newton's laws, momentum and impulse, then applies conservation of momentum to collisions, distinguishing elastic collisions from inelastic ones.
