m/s. One of the riders is a small girl of mass 40 kg. At points B
and C, the track is circular with the radii of curvature given in
the figure. The heights at points A, B, and C are hA= 24.9 m, hB =
34.75 m, and hC=0 m. You may assume the track is frictionless.

ar = 10 m The roller coaster in Figure P6.36 starts with a velocity of 15.7 m/s. One of the riders is a small girl of mass 36 kg. At points B and C, the track is circular with the radii of curvature given in the figure. The heights at points A, B, and C are ha= 24.15 m, hB = 34.1 m, and hc=0 m. You may assume the track is frictionless. Find the velocity of the roller coaster...
Problem 1 You are designing a roller coaster, shown in the figure below. An empty car has a mass of 120 kg. The radius of the vertical loop in the track is 12.0 m and the bottom of the loop is 5.0 m above the ground. Assuming the roller coaster is frictionless, how high must the car initially climb above the ground (point A) such that the speed of the car is 25.0 m/s at the top of the loop...
A roller-coaster track has six semicircular "dips" with different
radii of curvature. The same roller-coaster cart rides through each
dip at a different speed.For the different values given for the radius of curvatureR and speed v,
rank the magnitude of the force of the roller-coaster track on the
cart at the bottom of each dip.A) R=60m v=16 m/s B) R=15m v= 8m/s C) R=30m v= 4m/s D) R=45m v=
4m/s E) 30m v= 16 m/s F) R= 15m v=12 m/s
7.4 (P 7.41) 7.41 . A 350-kg roller coaster car starts from rest at point A and slides down a frictionless loop-the-loop (Fig. P7.41). (a) How fast is this roller coaster car moving at point B? (b) How hard does it press against the track at point B? Figure P7.41 14.00 m 25.0 m 12.0 m 3.00 m
ρ 30 m The roller-coaster track shown is contained in a vertical plane. The portion of track between A and B is straight and horizontal, while the portions to the left of A and to the right of B have radii of curvature as indicated. A car is traveling at a speed of 72 km/h when the brakes are suddenly applied, causing the wheels of the car to slide on the track (u 0.20 Determine the initial deceler ation of...
1) The figure shows a famous roller coaster ride. You can ignore friction. If the roller coaster leaves point Q from rest, what is its speed at the top of the 25-m peak (point S)? rm 50 m A) 22 m/s B) 10 m/s C) 62 m/s D) 120 m/s E) 44 m/s
9) A roller coaster is moving with an initial velocity of 5 m/s on a level track that is hi - 25 m off the ground, it goes down the ramp and back up a second ramp to a level track that is h2 - 10 m off the ground, A) What is the velocity of the roller coaster when it arrives at the lower surface (A)? Identify variables and their values. Vi=5 mi Write the full equation(s) used to...
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...
