Final answer:
Snowball A moves horizontally and snowball B moves at an angle of 35 degrees above the horizontal.
Step-by-step explanation:
To find the direction of motion of the snowballs just before they land, we need to analyze the horizontal and vertical components of their velocities.
Snowball A is thrown horizontally, so its velocity in the horizontal direction remains constant throughout its motion. The vertical component of its velocity is zero.
The angle at which snowball B is hurled is 35 degrees above horizontal. We can use trigonometry to determine the vertical component of its velocity. The vertical component is given by: v_vertical = v initial * sin(theta), where v_initial is the initial speed of the snowball and theta is the angle of its trajectory.
Therefore, the direction of motion of snowball A is horizontal, while the direction of motion of snowball B is at an angle of 35 degrees above the horizontal.
