**Help Please -- Ball swinging from a rope**

## Homework Statement

A ball of mass 30 kg is hanging from a rope of 3 meter tied to the roof of a truck. The truck is moving at a constant speed of 29.6 m/s. As you look forward at the ball hanging from the roof of the truck, you see the ball hanging to the right at an angle 45 from the horizontial.

1-What is the net force acting on the ball?

2-What is the radius of the curved path of the ball if one viewed the ball from overhead?

## Homework Equations

marad=m(v^2/r)

## The Attempt at a Solution

For part 1, I think you would just solve for the net force using marad but I just wanted confrim.

For part two, I have no idea where to even begin.
