Question

A baseball is thrown at an angle of 30° with respect to the ground and it reaches the ground in 2 seconds. What is its initial velocity of baseball?

Answer 1

Answer:

The answer to your question is vo = 19.62 m/s

Step-by-step explanation:

Data

angle = α = 30°

time = t = 2 s

vo = ?

g = 9.81 m/s²

Formula

                  $t = \frac{2vosin\alpha}{g}$

Solve for vo

             $vo = \frac{tg}{2sin\alpha}$

Substitution

            $vo = \frac{(2)((9.81)}{2sin 30}$

Simplification

           $vo = \frac{19.62}{2(0.5)}$

           $vo = \frac{19.62}{1}$

Result

            vo = 19.62 m/s
