question_answer 53)

  Obtain a relation for the distance travelled by an object moving with a uniform acceleration in the interval between 4th and 5th second.

Answer:

  From second equation of motion, Distance travelled in t see Distance travelled in 4 s (distance travelled in 4th sec) Again, distance travelled in 5 s                                 ( distance travelled in 5th sec) So, distance travelled in the interval between 4th and 5th second. So, the relation will be [u + 9/2a)
