A pick up van negotiates an unbanked curve of radius 40 m with a crate of eggs in the middle of its flat bed. If the coefficient of static friction between the crate and the truck, is 0.55 what is the maximum speed the van can take, so that the crate does not slide ?

Explanation

To solve the problem, we need to find the maximum speed of the pickup van such that the crate does not slide off the flatbed while negotiating an unbanked curve. We will use the formula for maximum speed based on the coefficient of static friction and the radius of the curve.

### Step-by-Step Solution:

1. **Identify the Given Values**:
- Radius of the curve, \( R = 40 \, \text{m} \)
- Coefficient of static friction, \( \mu = 0.55 \)
- Acceleration due to gravity, \( g = 9.8 \, \text{m/s}^2 \)
