Centripetal Force

A particle, body, object or certain mass while travelling in a rotational path or semicircular path, experiences an inertia force. If that inertia force pulls the towards the inward of the imaginary circle in the rotation, it is termed as centripetal force.

An object moves in a circular path at a constant speed. What is the relationship between the directions of the object's velocity and acceleration vectors? The velocity vector points in a direction tangent to the circular path. The acceleration is zero. The velocity and acceleration vectors are perpendicular. The velocity and acceleration vectors point in opposite directions. The velocity and acceleration vectors point in the same direction. The velocity vector points toward the center of the circular path. The acceleration is zero.
You are a jungle scientist. Your boss gives you the following alligator dive diagram. Your boss informs you of some key information. The gator travels at the top of the swamp surface 100m west and then 90.0m in a direction 33.0 degrees to the east of north. Then the gator dives below the swamp surface and travels an additional distance in an unknown direction. The final location of the gator is 60.0 m directly under a float marker which is placed 125m north of the gator's start location. Find what the gator's displacement was during this gator dive.
