What are the signs of position, velocity, and acceleration of a ball thrown upwards with an initial speed of 29.4 m/s at its highest point and during its upward and downward motions, with the following conventions: - x = 0 m and t = 0 s at the highest point - Vertically downward direction as the positive x-axis direction

Options

  1. AAt the highest point: Position is positive, velocity is zero, acceleration is positive. During upward motion:
  2. BAt the highest point: Position is positive, velocity is zero, acceleration is negative. During upward motion:
  3. CAt the highest point: Position is zero, velocity is zero, acceleration is positive. During upward motion: Posi
  4. DAt the highest point: Position is zero, velocity is zero, acceleration is negative. During upward motion: Posi

Correct answer

B. At the highest point: Position is positive, velocity is zero, acceleration is negative. During upward motion:

Step-by-step solution

Correct Option is : (B) At the highest point: Position is positive, velocity is zero, acceleration is negative. During upward motion: Position is positive, velocity is positive, acceleration is negative. During downward motion: Position is positive, velocity is negative, acceleration is positive.
