During a baseball game, a batter hits a high pop-up. if the ball remains in the air for a total of 6.0 s, how high does it rise? ( Assume Accel. = 10 m/s^2 )

Answer :

  • Time=6s
  • Vertex height's time= 6/2=3s
  • Acceleration due to gravity=10m/s^2

Apply second equation of kinematics

[tex]\\ \rm\hookrightarrow s=ut+\dfrac{1}{2}gt^2[/tex]

[tex]\\ \rm\hookrightarrow s=1/2(10)(3)^2[/tex]

[tex]\\ \rm\hookrightarrow s=5(9)[/tex]

[tex]\\ \rm\hookrightarrow s=45m[/tex]

It rises 45m
