Alice has a mass of 70.0 kg and her car has a mass of 1000.0 kg. Alice is sitting in parked car on the side of the road. The magnitude of the normal force exerted by the road on her car is? (use g = 9.81 m/s2)
1070g, of course
To find the magnitude of the normal force exerted by the road on Alice's car, we need to consider the forces acting on the car in the vertical direction.
The normal force represents the force exerted by a surface to support the weight of an object resting on it. In this case, the normal force is the force exerted by the road to support the car and Alice.
In a situation where the car is parked on a level road, the normal force is equal in magnitude and opposite in direction to the weight of the car and Alice combined.
The weight of an object is given by the equation:
Weight = mass × acceleration due to gravity
For Alice's car, with a mass of 1000.0 kg and acceleration due to gravity g = 9.81 m/s^2, the weight of the car is:
Weight = 1000.0 kg × 9.81 m/s^2 = 9810 N
Therefore, the magnitude of the normal force exerted by the road on the car is also 9810 N.
