Question

From the top of a tower two stones, whose masses are in the ratio 1 colon 2 are thrown one straight up with an initial speed u and the second straight down with the same speed u. Then, neglecting air resistance

  1. The heavier stone hits the ground with a higher speed  
  2. The lighter stone hits the ground with a higher speed  
  3. Both the stones will have the same speed when they hit the ground  
  4. The speed can’t be determined with the give data  

The correct answer is: Both the stones will have the same speed when they hit the ground
