Answer :

  • Initial velocity=u=0.3m/s
  • Final velocity=v=0.7m/s
  • Time=t=30s

[tex]\\ \sf\longmapsto Acceleration=\dfrac{v-u}{t}[/tex]

[tex]\\ \sf\longmapsto Acceleration=\dfrac{0.7-0.3}{30}[/tex]

[tex]\\ \sf\longmapsto Acceleration=\dfrac{0.4}{30}[/tex]

[tex]\\ \sf\longmapsto Acceleration=0.01m/s^2[/tex]
