Mechanic Question, involving linear motion
A ball is thrown straight up with an initial speed of 30 m/s. How high does it go, and how long is it in the air (neglecting air resistance)?
Please show step by step, and if possible, as a attached file.
Thank you.

u = 30 m/s
v = 0 m/s
a = -g
Use the equation to solve the distance it travels.
$$v^2=u^2+2as$$
