Question

A baseball leaves Sammy Sosa's Bat at 76 m/s 57 degrees above the horizontal. How long is it in the air? assume the bat is 1m above ground level when it contacts the ball

Answer 1

use a function to model height of ball...using acceleration due to gravity as 9.8 m/s^2
\[h(t) = -4.9t^{2} +v_o t +1\]
where v is initial velocity determined by force and angle of bat
\[v_o = 76 \sin(57)\]

Answer 2

set h(t) = 0 and solve for "t" using quadratic formula

Answer 3

kk thx man
