In an amusement park, a car rolls on a track as shown below.
Find the speed (in m/s) of the car at A, B, and C. Note that the
work done by the rolling friction is zero since the point at which
the rolling friction acts on the tires is momentarily at rest and
therefore has a zero displacement.
Va = ? m/s
Vb = ? m/s
Vc = ? m/s
Thanks!

At an amusement park, a car of mass m rolls without friction around a track as shown. The car starts from rest at point A, a height h = 3R above the bottom of the loop (R is the radius of the loop). Treat the car as a point-like particle. (a) Draw the free body diagram for the car and find the car’s kinetic energy and normal force acting on the car at the top of the loop (point B)....
A car in an amusement park ride rolls without friction around a
track (Figure 1). The car starts from rest at point A at a height h
above the bottom of the loop. Treat the car as a particle.
Figure 1:
PART A:
What is the minimum value of h (in terms of R) such that the car
moves around the loop without falling off at the top (point B)?
PART B:
If the car starts at height h= 4.30...
90 m (15 points) A roller coaster ride at an amusement park lifts a car of mass 700 kg to point A at a height of 90 m above the lowest point on the track, as shown above. The car starts from rest at point A. rolls with negligible friction down the incline and follows the track around a loop of radius 20 m. Point B. the highest point on the loop, is at a height of 50 m above...
A car in an amusement park roller coaster ride rolls without friction at the top of a hill. The car begins at a height h from the top of a hill. A the bottom, the car then goes through a vertical loop where the car is upside down at the loop\'s top. If the radius of the loop is 20.0m, what is the minimum height h such that the car moves around the loop without falling off the track at...
In an amusement park, a 250 kg roller coaster reaches point A
with velocity of 8 m/sec. What is its velocity at point B if the
work done by friction of the track is 3000 joules during this
displacement from A to B?
? 8.0 m/s 8.0 m A 5.0 m B
? 8.0 m/s 8.0 m A 5.0 m B
A marble rolls on the track shown
in the figure below, with hB = 24 cm and hC = 12 cm. If the marble
has a speed of 2.0 m/s at point A, what is its speed at points B
and C?
Velocity at point B _______ m/s
Velocity at point C________ m/s

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.

2. The amusement park ride consists of a 200-kg car and passenger that are traveling at 3 m/s along a circular path having a radius of 8 m (horizontal plane) If at t 0, the cable OA is pulled in toward O at 0.5 m/s, determine: a. Is energy conserved? why? (5%). b. Is angular momentum about point O conserved? why? (596). C. The speed of the car when t-4 s (10%). d. work done to pull...
