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...

Problem 2 – variation of problem 10.76: A thin- walled, hollow spherical shell of mass m and radius r starts from rest and rolls without slipping down the track shown in the figure. Points A and B are on a circular part of the track having radius R. The diameter of the shell is very small compared to ho and R, and the work done by rolling friction is negligible. a) What is the minimum height ho, for which this...

A tennis ball is a hollow sphere with a thin wall It is set rolling without slipping at 4.12 m/s on a horizontal section of a track as shown in the figure below. It rolls around the inside of a vertical circular loop of radius r = 46.7 cm. As the ball nears the bottom o the oop, the shape o the track deviates rom a perfect circe so that the bal eaves the track at a point 80 cm...

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...

A stationary ball is let go from the top of a 75 cm long
diagonal table. It rolls down and off the edge, free falls and hits
the ground.
a) If it takes the ball 0,797 seconds to roll down the table
before it goes off the edge, what is it's average speed?
b) What is the balls speed when it goes off the edge? Formula for
even acceleration is Vm = (V0+V)/2
c) What is the horizontal speed of...

In the figure here, a solid brass ball of mass 0.298 g will roll
smoothly along a loop-the-loop track when released from rest along
the straight section. The circular loop has radius R =
0.19 m, and the ball has radius r <<
R.
(a) What is h if the ball is on the verge
of leaving the track when it reaches the top of the loop?
(b) If the ball is released at height h =
7R, what is...

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)....

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...

I just need help with part c) please/thank you A solid brass ball of mass 20.9 g and radius 8.37 mm rolls smoothly along a loop-the-loop track when released from rest from a tall ramp leading to the loop-the-loop. The circular loop has a 12 cm radius. (a) What is the minimum height from which you can release the ball so that it will go around the loop-the-loop without falling off? 32.4 cm Correct: Your answer is correct. For part...
