Nancy is pushing her empty grocery cart at a rate of 1.8 m/s. 30 seconds later,
she is pushing the, now full cart, at a rate of 0.54 m/s. Calculate the acceleration
of the cart.

Respuesta :

  • initial velocity=u=1.8m/s
  • Time=t=30s
  • Final velocity=v=0.54m/s

[tex]\\ \bull\tt\dashrightarrow Acceleration=\cfrac{v-u}{t}[/tex]

[tex]\\ \bull\tt\dashrightarrow Acceleration=\dfrac{0.54-1.8}{30}[/tex]

[tex]\\ \bull\tt\dashrightarrow Acceleration=\dfrac{-1.26}{30}[/tex]

[tex]\\ \bull\tt\dashrightarrow Acceleration=-0.042m/s^2[/tex]
