If you do this question for me you'll get 100 points!

A room worker was dropped from the roof of a building in free fall. find the following:
1- The velocity of the stone after a time of 5 s.
2- The displacement of the stone within (s 5).
Take the acceleration of free fall g = 9.8 m/s2

Respuesta :

#1

  • Initial velocity=u=0m/s
  • Time=t=5s
  • Acceleration=a=9.8m/s^2

Final velocity=v

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

[tex]\\ \sf\longmapsto v=0+5(9.8)[/tex]

[tex]\\ \sf\longmapsto v=49m/s[/tex]

#2

  • Displacement=s

[tex]\\ \sf\longmapsto s=ut+\dfrac{1}{2}at^2[/tex]

[tex]\\ \sf\longmapsto s=0(5)+\dfrac{1}{2}(9.8)(5)^2[/tex]

[tex]\\ \sf\longmapsto s=4.9(25)[/tex]

[tex]\\ \sf\longmapsto s=122.5m[/tex]
