Question

A packet is dropped from a balloon which is going upwards with the velocity 12 blank m divided by s , the velocity of the packet after 2 seconds will be

  1. negative 12 blank m divided by s  
  2. 12 blank m divided by s  
  3. negative 7.6 blank m divided by s  
  4. 7.6 blank m divided by s  

The correct answer is: negative 7.6 blank m divided by s


    When packet is released from the balloon, it acquires the velocity of balloon of value 12 blank m divided by s. Hence velocity of packet after 2 blank s e c, will be
    v equals u plus g t equals 12 minus 9.8 cross times 2 equals negative 76 blank m divided by s
