  • Initial velocity=u=72km/h

Convert to m/s

[tex]\\ \rm\Rrightarrow 72\times \dfrac{5}{18}=20m/s[/tex]

  • Acceleration=a=-2m/s^2
  • Time=t=5s
  • Final velocity=v

[tex]\\ \rm\Rrightarrow v=u+at[/tex]

[tex]\\ \rm\Rrightarrow v=20+(-2)(5)[/tex]

[tex]\\ \rm\Rrightarrow v=20-10[/tex]

[tex]\\ \rm\Rrightarrow v=10m/s[/tex]
