A section of track for a roller coaster consists of two circular arcs AB and CD joined by a straight portion BC. The radius of AB is 27 m and the radius of CD is 72 m. The car and its occupants, of total mass 300 kg, reach point A with practically no velocity and then drop freely along the track. Determine the maximum and minimum values of the normal force exerted by the track on the car as the...

Consider the track shown in the figure above. The section AB
is one quadrant of a circle of radius r and is frictionless. B to C
is a horizontal span of length L with a coefficient of kinetic
friction μk. The section CD under the spring is frictionless. A
block of mass m is released from rest at A. After sliding on the
track, it is observed to compress the spring by a distance d.

P6 A car travels around a circular track at constant speed, as shown. It is observed that the car takes 15.71 seconds to go from point A to point B along the track (exactly a quarter circle). An accelerometer mounted on the car shows that its acceleration has a constant magnitude of 7.0 m/s2. Please answer each of the following questions. For answers that require vectors, refer to the instant shown in the figure. a) What is the radius of...
