Question

A baseball player tosses a baseball upward giving it an initial velocity of 8.20 m/s. How long does it take for the baseball to reach its maximum height? 

Answer 1

We can find the time that the ball takes to reach its maximum height from the kinematic equation:

$$v=v_0-gt,$$ $$0=v_0-gt,$$ $$t=\dfrac{v_0}{g}=\dfrac{8.20\ \dfrac{m}{s}}{9.8\ \dfrac{m}{s^2}}=0.84\ s.$$

Answer:

$t=0.84\ s.$
