Let’s analyze the wording of the problem:

- A conical pendulum is a swinging pendulum that can rotate around an axis. The bob (the mass) will have circular path at all angles θ, but here we need to investigate when the angle is 5°.
- When a body moves is circular motion it must have at least a radial acceleration (centripetal acceleration).
- The mass is connected by a wire, the wire will have a tension (because it is used to suspend the bob). The tension should have x- and y-components.

What the information give in problem:

- The bob’s mass (m) = 80 kg
- Length of wire (L) = 10 m
- Angle of pendulum (θ) = 5°

What the problem need:

- The x- and y-components of tension force.
- The radial acceleration

SOLUTION:

- The x- and y-components of tension force.
- The x- and y-components of the tension force are:

- The radial acceleration
