Question

A cricket ball is thrown up with a speed of 19.6 blank m s to the power of negative 1 end exponent. The maximum height it can reach is

  1. 9.8 blank m  
  2. 19.6 blank m  
  3. 29.4 blank m  
  4. 39.2 blank m  

The correct answer is: 19.6 blank m


    H subscript m a x end subscript equals fraction numerator u to the power of 2 end exponent over denominator 2 g end fraction equals fraction numerator 19.6 cross times 19.6 over denominator 2 cross times 9.8 end fraction equals 19.6 blank m
