A particle moves in a straight line. It starts from a fixed point O. Its acceleration, a m <^ - 2 is given by a = 2t + 1 where t is the time in seconds after passing through point O. Its initial velocity is -6 m S ^ - 1
Find the total distance travelled by the particle in the first 4 seconds.
Ans:20m
U can use the displacement-time graph method instead of motion diagram method
