Question

Three balls are dropped from the top of a building with equal speed at different angles. When the balls strike ground their velocities are v subscript 1 end subscript comma v blank subscript 2 end subscript and v subscript 3 end subscript respectively, then

  1. v subscript 1 end subscript greater than v subscript 2 end subscript greater than v subscript 3 end subscript    
  2. v subscript 3 end subscript greater than v subscript 2 end subscript greater than v subscript 1 end subscript    
  3. v subscript 1 end subscript equals v subscript 2 end subscript equals v subscript 3 end subscript    
  4. v subscript 1 end subscript less than v subscript 2 end subscript less than v subscript 3 end subscript    

The correct answer is: v subscript 1 end subscript equals v subscript 2 end subscript equals v subscript 3 end subscript


    All the balls are projected from the same height, therefore their velocities will be equal.
    S o comma blank v subscript 1 end subscript equals v subscript 2 end subscript equals v subscript 3 end subscript
