A car with a mass of 1000.0 kg is travelling over the top of a hill, as shown in Figure 7. The hill’s curvature has a radius of 40.0 m, and the car is travelling at 15 m/s. (a) Draw an FBD. (b) Determine the magnitude of the normal force between the hill and the car at the top of the hill. (c) Determine the speed required to make the driver feel weightless at the top of the hill.

Step 1
(a) For the FBD, we have the following forces acting on the car: - Gravitational force (weight) acting downward: $F_g = mg$ - Normal force acting perpendicular to the surface of the hill: $F_n$ Show more…

A car of mass $1000 \mathrm{kg}$ is traveling over the top of a hill as shown in Eigure $\mathrm{P} 5.21$ a. If the hill has a radius of curvature of $40 \mathrm{m}$ and the car is traveling at $15 \mathrm{m} / \mathrm{s},$ what is the normal force between the hill and the car at the top of the hill? b. If the driver increases her speed sufficiently, the car will leave the ground at the top of the hill. What is the speed required to make that happen?

A car of mass 1500 kg goes over a hill at a speed of 20 m/s. The shape of the hill is approximately circular, with a radius of 60 m, as in the figure at right. When the car is at the highest point of the hill, What is the force of gravity on the car? What is the normal force of the road on the car at this point?

A car with a mass of $1000 .$ kg goes over a hill at a constant speed of $60.0 \mathrm{~m} / \mathrm{s}$. The top of the hill can be approximated as an arc length of a circle with a radius of curvature of $370 . \mathrm{m}$. What force does the car exert on the hill as it passes over the top?
