0.40 kg ball is thrown with a speed of 9 m/s at an upward angle of 29°.

(a) What is its speed at its highest point? (Use conservation of energy.)

2. Relevant equations

Work of non conservative forces = change in KE + change in PE

3. The attempt at a solution

I am not sure how to go about this.
