someone please help me with my homework !!!!

1. Homework Statement

A kicked soccer ball has an initial velocity of 25 meters per second at an angle of 40 degrees above the horizontal level ground [neglect friction]

A)calculate the magnitude of the vertical component of the balls initial velocity

b) calculate the maximum height of the ball reaches above its initial speed

c) sketch the balls height from the its initial position at point p until it returns to level ground

2. Homework Equations

A) Viy sin 40 degrees

B) dy= vytrise is this the correct equation?

c) im not sure how i can sketch it yet

3. The Attempt at a Solution

im confused with the 2nd problem how can i find maximum height if somoene can explain to me that wll help alot ^-^

At the maximum height, the instantaneous vertical velocity of the ball must be zero.
