Question

A body of 5 blank k g is moving with a velocity of blank 20 m divided by s. If a force of 100 N is applied on it for 10 sin the same direction as its velocity, what will now be the velocity of the body

  1. 200 blank m divided by s  
  2. 220blank m divided by s  
  3. 240blank m divided by s  
  4. 260blank m divided by s  

The correct answer is: 220blank m divided by s


    v equals u plus a t equals u plus open parentheses table row cell fraction numerator F over denominator m end fraction end cell row cell end cell end table close parentheses t equals 20 plus open parentheses table row cell fraction numerator 100 over denominator 5 end fraction end cell row cell end cell end table close parentheses cross times 10 equals 220 blank m divided by s
