Answer to Question #136598 in Mechanics | Relativity for Banakeng

Question

A baseball is hit so that it travels straight upward after being struck by the bat. A fan observes that it takes 3.00 s for the ball to reach its maximum height. Find (a) the ball’s initial velocity and (b) the height it reaches.

Answer 1

(a)

$v=gt=9.8\cdot3=29.4$ ($\frac{m}{s}$ )

(b)

$h=\frac{gt^2}{2}=\frac{9.8\cdot3^2}{2}=44.1$ ($m$ )
