Correction and Comments about Numericals and Short Question Answers

  • Numerical 2.9
    Question Asked by Maria Khan : The answer of numerical 2.9 of 2nd part where the distance is asked to find is, not coming correct.so please check this.your answer is 266.53m but through calculator is 296.14m.plz solve this query.
    Answer : Actually, the value of 266m comes when you do not round off the value of acceleration (means a= -0.3331666875 m/s*s) and all other velocities. So your answer is also correct because you round off the value of acceleration. In exams I would say that write the value of distance 296m because this is the value you computed after rounding off and it is correct also.
  • Numerical 2.8
    Problem : Incomplete Numerical and missing page number 14.
    Remaining Part:
    0 = 6vi – 180
    vi = 30m/s
    Now calculating height reached by the ball
    using formula 2as = vf2 – vi2
    putting values in the above formula
    s = (vf2 – vi2)/2a
    s = (0 – 30*30)/2*9.8
    s = 45m approx
    Hence the height reached by the ball is 45 meters and the initial velocity is 30 m/s
