A ball with an initial velocity of zero is dropped from a table onto the ground. After 2 s, the
ball hits the ground. Approximately how fast is the ball traveling when it hits the ground?
10m/s
20m/s
30m/s
40m/s

Respuesta :

  • Initial velocity=u=0m/s
  • Acceleration=a=10m/s^2
  • Time=t=2s

Final velocity=v

[tex]\\ \sf\longmapsto v=u+at[/tex]

[tex]\\ \sf\longmapsto v=0+10(2)[/tex]

[tex]\\ \sf\longmapsto v=20m/s[/tex]
