3. A frictionless roller-coaster goes around a circular loop of radius 11 m. It enters the bottom of the loop going 32 m/s. Find the speed of the roller-coaster when it gets to the top of the loop 4. For the loop in the previous problem find the velocity of the roller-coaster as a function of height off the ground. Use that to find the centripetal acceleration as a function of height. Plot the centripetal acceleration as a function of...

PLEASE ANSWER CORRECTLY THE CORRECT ANSWER IS 46
A roller coaster cart starts at the top of a quarter circular
hill (no friction) of some radius at a speed of 11.8
m/s. At the bottom of the hill it encounters a
horizontal surface with friction and the coefficient of kinetic
friction is 0.55. It travels over that horizontal surface for 8
meters and encounters a frictionless loop with a radius of 23
meters. If it is to just barely make...

Problem 2 A 1 kg block slides down a ramp and then around a circular loop of radius 11 m, as shown in diagram below. Considering there is no friction, find the minimum height of the ramp so that block makes all the way around the loop without falling. Write the expression for initial energy of the system ii) Write the expression for energy of the system at the top of the loop. lii) Draw Free body diagram at the...

You are designing the section of a roller coaster ride shown in the figure. Previous sections of the ride give the train a speed of 14.3 m/s at the top of the incline, which is h=37.9 m above the ground. As any good engineer would, you begin your design with safety in mind. Your local government's safety regulations state that the riders' centripetal acceleration should be no more than n=1.61 g at the top of the hump and no more...

A rollercoaster cart with a mass of 11 kg is travelling around a
vertical loop (circle) with a radius of 8 meters. At the top, it's
traveling at the minimum speed needed so that it remains in contact
with the track. If at some short time later it is at the side of
the loop (halfway between the top and bottom), what is the normal
force on the cart, in Newtons, if it loses 147 Joules of work to
non-conservative...

(10%) Problem 10: Modem roller coasters have vertical loops like the one shown in the figure. The radius of curvature is smaller at the top than on the sides so that the downward centripetal acceleration at the top will be greater than the acceleration due to gravity, keeping the passengers pressed firmly into their seats.
