I need help with the last three questions the Loop A mass m -82 kg slides...
A bead slides on a wire without friction around a loop-the- loop of radius 1.1 m. The bead is released with a speed 0.1 m/s from a height h 3 m whereh is measured from the bottom of the loop. What is the magnitude of the normal force (in N) on the bead at the top of the loop, if its mass is 5 gr(do nat include units in your answer)
A marble of mass m and radius r rolls along
the looped rough track of the figure.(Figure 1) Ignore frictional
losses.
Part A
What is the minimum value of the vertical height h that
the marble must drop if it is to reach the highest point of the
loop without leaving the track? Assume r?R.
Express your answer in terms of R.
Part B
What is the minimum value of the vertical height h that
the marble must drop if...
A solid marble of mass m = 35 kg and radius r = 4
cm will roll without slipping along the loop-the-loop
track shown in the figure if it is released from rest somewhere on
the straight section of track. From what minimum height h above the
bottom of the track must the marble be released to ensure that it
does not leave the track at the top of the loop? The radius of the
loop-the-loop is R = 1.05...
Consider a solid sphere of mass m and radius r being released
from a height h (i.e., its center of mass is initially a height h
above the ground). It rolls without slipping and passes through a
vertical loop of radius R.
a. Use energy conservation to determine the tangential and
angular velocities of the sphere when it reaches the top of the
loop.
b. Draw a force diagram for the sphere at the top of the loop
and write...
Problem 9 m,r A solid ball of mass m and radius r sits at rest at the top of a hill of height H leading to a circular loop-the loop. The center of mass of the ball will move in a circle of radius R if it goes around the loop. The moment of inertia of a solid ball is Ibull--mr. (a) Find an expression for the minimum height H for which the ball barely goes around the loop, staying...
A small block of mass m slides along the frictionless loop the loop track shown below. If it starts from rest at point A, what is the speed of the block at point B? (v = squareroot (10 g R)) What is the net force acting on the block at point C? (Don't forget the gravitational force. (F = -mg (8i + j) At what height above the bottom should the block be released so that the normal force exerted...
A roller coaster car of mass 800 kg when released from rest at
point A (height h above the ground) slides along the track and
inside the loop of radius 16.0 m. The car never loses contact with
the track.
A) Draw below a free body diagram for the car the car at the top
of the loop.
B) If the normal force acting on the car at the top is 1500 N,
what is the speed of the car...
A bead slides on a wire without friction around a loop-the-loop of radius 1.3 m. The bead is released with a speed 0.7 m/s from a height h=3.6 m where his measured from the bottom of the loop. How large is the normal force (in N) on the bead at the bottom of the loop, if its mass is 5 g?

Review Part A The marble rolls down the track and around a loop-the- loop of radius R. The marble has mass m and radius r.(Figure) What minimum height h must the track have for the marble to make it around the loop-the-loop without falling off?
