1. The problem statement, all variables and given/known data 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 2. Relevant equations F_gravity=mg F_centripetal=m(a_centripetal) a_centripetal = m (v^2/r) 3. 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?
