An ice skater starts with a velocity of 2.25 m/s in a 50.0°
direction. After 8.33 s, she is
moving 4.65 m/s in a 120°
direction. What is the
y-component of her acceleration?

Suppose a soccer ball is kicked from the ground at an angle 20.0º above the horizontal at 8.00 m/s. the y-velocity is determined to be 2.74 m/s. how long will the ball be in the air? assume the ball lands at the same height at which it was kicked.
