Question

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

Answer 1

Explanation:

5

5

m/s2

lol

Answer 2

#1

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

Final velocity=v

`\\ \sf\longmapsto v=u+at`

`\\ \sf\longmapsto v=0+5(9.8)`

`\\ \sf\longmapsto v=49m/s`

#2

• Displacement=s

`\\ \sf\longmapsto s=ut+(1)/(2)at^2`

`\\ \sf\longmapsto s=0(5)+(1)/(2)(9.8)(5)^2`

`\\ \sf\longmapsto s=4.9(25)`

`\\ \sf\longmapsto s=122.5m`
