Calculation of the Force Exerted by the Car on the Bridge

To calculate the force exerted by the car on the bridge, we need to consider the centripetal force acting on the car as it moves along the curved bridge. The centripetal force is responsible for keeping the car moving in a curved path and is directed towards the center of the circular motion.

The formula to calculate the centripetal force is:

F = (m * v^2) / r

Where: - F is the centripetal force - m is the mass of the car (1000 kg) - v is the velocity of the car (36 km/h or 10 m/s) - r is the radius of curvature of the bridge (50 m)

Let's plug in the values and calculate the force:

F = (1000 kg * (10 m/s)^2) / 50 m

Simplifying the equation:

F = (1000 kg * 100 m^2/s^2) / 50 m

F = 2000 N

Therefore, the car exerts a force of 2000 Newtons on the bridge at its midpoint.

Please note that this calculation assumes ideal conditions and does not take into account other factors such as friction or the weight distribution of the car.
