Gabriela is playing with her toy rattle, and decides to toss the rattle in the air at a 90 degree angle. The initial velocity of the rattle is +7 m/s Kristy claims that the rattle would achieve a higher height if it were launched at a 62 degree angle. Is Kristy correct? Explain your answer

Gabriela is playing with her toy rattle, and decides to toss the rattle in the air at a 90 degree angle. The initial velocity of the rattle is +7 m/s

1.Kristy claims that the rattle would achieve a higher height if it were launched at a 62 degree angle. Is Kristy correct? Explain your answer.
Kristy is incorrect

2.What is the velocity of the rattle be when it returns to Gabriela? Explain how you know.
