A particle moves in a straight line. It has a velocity of $6 m{s}^{-1}$ when it is subjected to an acceleration of $-3m{s}^{-2}$ for $3$ seconds. It maintains a uniform velocity for $2$ seconds and is then brought to rest in a time of $2$ seconds.
1. Total distance covered$=19.5 m$
2. Acceleration between $5-7$ sec is $1.5 \frac{m}{s^2}.$
3. Magnitude of displacement $0-3$ sec is $4.5 m$.
4. Magnitude of displacement $0-7$ sec is $7.5 m$.
5. Distance average m $0-5$ sec is $13.5 m$.
Which of above statements are correct?
