## Homework Statement

**A car travels along the perimeter of a vertical circle (radius = 0.25 km) at a constant speed of 30 m/s. What is the magnitude of the resultant force on the 60-kg driver of the car at the lowest point on this circular path?**

**Question options:**

**1) 0.37 kN**

**2) 0.80 kN**

**3) 0.22 kN**

**4) 0.59 kN**

**5) 0.45 kN**

## Homework Equations

F_gravity=mg

F_centripetal=m(a_centripetal)

a_centripetal = m (v^2/r)

## The Attempt at a Solution

F=mg + ma_centripetal = m (g + a_centripetal) = 60 kg (9.8 m/s^2 + (30m/s)^2/(250m)) = 804N = 0.8kN

but the answer I got was different from the answer i got with the question which is 0.22kN

can someone please explain how is it 0.22kN?
