Question

A baseball is thrown at an angle of 25º relative to the ground at a speed of 23.0 m/s. If the ball is caught 42.0 m from where it is thrown, how long was it in the air?

Answer 1

`2.015 " seconds"`

Explanation:

`v_{0x} = 23 cos(25°)`
`x = 42 = v_{0x} t = 23 cos(25°) t`
`=> t = 42 / (23 cos(25°)) = 2.015 " seconds"`
