Question

A stone is projected vertically upward at t = 0 second from ground and collision betweenthe ground and the stone is perfectly elastic. The net displacement of stone between t0 second tot = T seconds is zero. The time of flight of stone is T. Pick up theINCORRECT statement.(A) From timet = T/4 second to t 3T/4 second, the average velocity is zero.(B) The change in velocity from time t = 0 to t = T/4 second is same as change invelocity fromt =T/8 second to t =3T/8 second.(C) The distance travelled from t = 0 to t = T/4 second is larger than the distancetravelled fromt = T/4 second to t =3T/4 second.(D) The distance traveled from t =T/2 second to t =3T/2 second is half the distance traveled from t = T/2 second to t =T second.
