Solve the given parts of following question:
Question: A 0.70kg ball is thrown with a speed of 18m/s at an angle of 26o.
Part I: What is its speed at its highest point?
Part II: How high does it go? (Use conservation of energy, and ignore air resistance.)
Please explain all work to calculate its speed at its highest point and express your answer using two significant figures.
