angular direction is ug. The unit vector in the tangent direction u, and the unit in the normal
direction vector is un.
for 0= 58°,
a) Acceleration and velocity in u, and ue directions.
b) Acceleration and velocity in the u, and u, direction and the radius of curvature.
c) If a force of -3000 * u„N affects the object during its movement, calculate the friction force
required to prevent the object from sliding in the normal axis. The friction force acts in the un
direction.
