Answer:
Acceleration, ![a=\dfrac{1}{8}(-i+9j)\ m/s^2](https://tex.z-dn.net/?f=a%3D%5Cdfrac%7B1%7D%7B8%7D%28-i%2B9j%29%5C%20m%2Fs%5E2)
Explanation:
Initial velocity of a particle in vector form, u = (-5i - 2j) m/s
Final velocity of particle in vector form, v = (-6i + 7j) m/s
Time taken, t = 8 seconds
We need to find the magnitude of acceleration vector. The changing of velocity w.r.t time is called acceleration of a particle. It is given by :
![a=\dfrac{v-u}{t}](https://tex.z-dn.net/?f=a%3D%5Cdfrac%7Bv-u%7D%7Bt%7D)
or
![a=\dfrac{1}{8}(-i+9j)\ m/s^2](https://tex.z-dn.net/?f=a%3D%5Cdfrac%7B1%7D%7B8%7D%28-i%2B9j%29%5C%20m%2Fs%5E2)
Hence, the value of acceleration vector is solved.
