The runner has initial velocity vector
and acceleration vector
so that her velocity at time is
She runs directly east when the vertical component of is 0:
It's not clear what you're supposed to find at this particular time... possibly her position vector? In that case, assuming she starts at the origin, her position at time would be
so that after 10.4 s, her position would be
which is 19.9 m away from her starting position.
C. The hitter has put a lot of external force on the ball.
Explanation:
- When high external force is applied to a ball that is hit harder, it flies farther
- Three forces act on the baseball in flight - lift, drag and weight
- Weight - directed towards earth's center
- Weight can be determined by Newton's laws of gravitation
- Drag - When the ball moves through air, a resistance force (drag) is applied to its motion
- Drag - Directed along and opposite to flight direction of the ball
- Lift - aerodynamic force perpendicular to the flight direction

Answer:
Option A
You need a Angle C congruent to angle F
Explanation:
EX) Side angle Side = sas
Answer:
Most likely it will reach 29.4 up in the air before coming back down.
Explanation:
The force of the ball will be the same on how high it will go.
