Question

A ball is thrown vertically upwards. Which of the following plots represents the speed-time graph of the ball during its flight if the air resistance is not ignored

  1.   
  2.   
  3.   
  4.   

The correct answer is:


    For upward motion
    Effective acceleration equals negative open parentheses g plus a close parentheses
    And for downward motion
    Effective acceleration equals left parenthesis g minus a right parenthesis
    But both are constants. So the slope of speed-time graph will be constant
