Question: A ball is shot from the ground into the air. At a height of 8.8 m, the velocity is observed to be v = (7.7)i + (5.7)j in meters per second (i horizontal, j upward). To what maximum height will the ball rise?
What will be the total horizontal distance traveled by the ball?
What is the velocity of the ball (magnitude and direction) the instant before it hits the ground? That is what is its i-component?
What is its j-component?
