The radius of curvature of the bridge is 100 m. The weight of the car is 2000 kg, its speed at the point is 5 m / s.

The radius of curvature of the bridge is 100 m. The weight of the car is 2000 kg, its speed at the point is 5 m / s. Determine the weight of the vehicle at the lowest point of the concave bridge.

Initial data: R (radius of curvature of the concave bridge) = 100 m; m (mass of the vehicle in question) = 2000 kg; V (speed at the lowest point) = 5 m / s.
Reference values: g (acceleration due to gravity) = 9.81 m / s2.
To determine the weight of the car in question at the lowest point of the bridge, we use the formula: P = m * (g + an) = m * (g + V ^ 2 / R).
Let’s perform the calculation: P = 2000 * (9.81 + 5 ^ 2/100) = 2000 * 10.06 = 20 120 N.
Answer: At the lowest point of the bridge, the weight of the vehicle in question will be 20 120 N.
