Question

A body of mass m is thrown upwards at an angle theta with the horizontal with velocity v. While rising up the velocity of the mass after t seconds will be-

  1. square root of left parenthesis v cos invisible function application theta right parenthesis to the power of 2 end exponent plus left parenthesis v sin invisible function application theta right parenthesis to the power of 2 end exponent end root    
  2. square root of left parenthesis v cos invisible function application theta minus v sin invisible function application theta right parenthesis to the power of 2 end exponent minus g t end root    
  3. square root of left parenthesis v to the power of 2 end exponent plus g to the power of 2 end exponent t to the power of 2 end exponent minus left parenthesis 2 v sin invisible function application theta right parenthesis g t end root    
  4. square root of left parenthesis v to the power of 2 end exponent plus g to the power of 2 end exponent t to the power of 2 end exponent minus left parenthesis 2 v cos invisible function application theta right parenthesis g t end root    

The correct answer is: square root of left parenthesis v to the power of 2 end exponent plus g to the power of 2 end exponent t to the power of 2 end exponent minus left parenthesis 2 v sin invisible function application theta right parenthesis g t end root
