r-20m 6-60m 2. Consider the image above that shows the trajectory of a roller coaster car. The roller coaster car has a mass of 200kg and is released from rest at position A. a. Find the velocity of the car at positions B, C, and D b. Determine the maximum possible radius of the circle such that the car will not lose contact with the track c. Suppose a breaking force (F 10 newtons) is applied as...

The figure below shows a roller-coaster car
on a track. The car is fully loaded with passengers and has a total
mass of 440 kg. At point A, the car is at the lowest point in a
circular arc of radius r1 = 12.6 m. At point B, the car is at the
highest point of a circular arc of radius r2 = 15.8 m.

1). the roller coaster car with a mass of 250 kg starts with an initial speed v0 = 5.6 m/s at the top of the track . What is its speed (in m/s) at the lowest point of the track (which is 25m below the start point)? Keep 2 decimal places. 1 b) Recall what you learned in vertical circular motion. If the lowest part of the track is approximated as circular with a radius of 6.20 m, What is the...

A roller-coaster car shown in the figure on the right is released from rest from a height h and then moves freely with negligible friction. The roller-coaster track includes a circular loop of radius R in a vertical plane. a. First suppose the car barely makes it around the loop; at the top of the loop, the riders are upside down and feel weightless. Find the required height h of the release point above the bottom of the loop in...

1. A roller coaster at an amusement park has a dip that bottoms out in a vertical circle of radius r. A passenger feels the seat of the car pushing upward on her with a force equal to twice her weight as she goes through the dip. If r = 28.7 m, how fast is the roller coaster traveling at the bottom of the dip? 2. A 0.21-kg ball on a stick is whirled on a vertical circle at a...

A car of mass 500. kg on a roller coaster ride is raised from
the ground (horizontal dotted line) to point A as shown in the
diagram above. When the car passes point A, its speed is 5.0 m/s,
and then it rolls freely through the rest of the ride with
negligible friction, passing points B, C, D and E. Note that point
D is the highest portion of a circular loop, and point E is the
lowest portion of...
