Answer:

height=.5*gravity*(time)^2

height=0.5*9.81*(2.34)^2

height= 26.85m

------

velocity= gravity*time

velocity = 9.81 * 2.34

velocity= 22.95 m/s

  • Time=t=2.34s
  • Acceleration=g=10m/s^2
  • Height=h
  • Final velocity=v

[tex]\\ \sf\longmapsto h=-\dfrac{1}{2}gt^2[/tex]

[tex]\\ \sf\longmapsto h=-5(2.34)^2[/tex]

[tex]\\ \sf\longmapsto h=-5(5.47)[/tex]

[tex]\\ \sf\longmapsto h=27.35m[/tex]

And

[tex]\\ \sf\longmapsto v^2=u^2+2gs[/tex]

[tex]\\ \sf\longmapsto v^2=(2.34)^2+2(10)(27.35)[/tex]

[tex]\\ \sf\longmapsto v^2=5.47+547[/tex]

[tex]\\ \sf\longmapsto v^2=552.47[/tex]

[tex]\\ \sf\longmapsto v\approx 23.5m/s[/tex]
