The correct Answer is:
C, D
Given `u=28 m/s, v=0, a =-g=-9.8 m/s^2, S_2 = (v^2-u^2)/(2a), =(0^2-28^2)/(2(-9.8)=2.85, t'=2.85-1=1=1.85, v'=u+at'=28-(9.8)(1.85), (28-18.13=9.87m/s` Hence the velocity is 9.87m/s. c. No it will not change. As, after one second velocity becomes zero for any initial velocity and deceleration is `g= 9.8 m/s^2` remains same. for initial velocity more than 28 m/s maximum height increases.
