If SA=2m+(2m+1)+(2m+2)+...+4m and SB=(2m+1)+(2m+3)+(2m+5)+...+(4m−1), then
A body has an initial velocity of 4 ms−1 and deceleration of 4 ms−2, then what is its final velocity after travelling 2 m?
A body has an initial velocity of 4 m/s and deceleration of 4 m/s2, then what is its final velocity after travelling 2m?
