A car starts at the bottom of a circular track with an inital velocity of 50m/s through a height of 10 m. The radius of the track is 10m. (A) Describe the resulting motion of the car if no energy is lost. (B) Find the position on the track where the normal force is zero. (C) Does the car loose contact with the track? Explain, (D) and calculate the maximum height the car reached on the track. (E) Is the velocity zero at the Max height? Explain with a picture.

A roller coaster car of mass 900 kg when released from rest at point A (height h above the ground) slides along the track and inside the loop of radius 15.0 m. The car never loses contact with the track. Draw below a free body diagram for the car at the bottom of the loop. If the speed of the car at the bottom of the loop (point B) is 25 m/s, what is the normal force at that point?...

An automobile moves on a circular track of radius 1.04 km. It starts from rest from the point (x, y) = (1.04 km, 0 km) and moves counterclockwise with a steady tangential acceleration such that it returns to the starting point with a speed of 29.2 m/s after one lap. (The origin of the Cartesian coordinate system is at the center of the circular track.) What are the car's position and velocity vectors when it is one-sixth of the way...

A jet accelerates at a=3.92 m/s^2 from rest until it reaches its takeoff velocity of 360 km/hr. It has to travel for 5 seconds at its takeoff velocity before taking off. What's the minimum distance that the jet will travel on the runway? A car backs up at a constant speed for a short time, then applies the brakes and steadily comes to rest. Sketch velocity-time and position-time graphs that depict the car's motion. Assume that the forward direction is...
