The graph given below gives the displacement of particle travelling along the X - axis as a function of time . AM is the tangent to the curve at the starting moment and BN is tangent at the end moment . Both the angles are 120 degrees.
i) what is average velocity during the first 20 seconds ?
ii) what is the average acceleration during the first 20 seconds ?
iii) what is time interval during which motion is retarded ?
IT'S A HUMBLE REQUEST PLEASE DO NOT GIVE SILLY ANSWERS OR SPAM ONE WHO KNOWS MUST ONLY ATTEMPT
