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.

A block of mass m slides down a frictionless ramp to a
loop of radius R, also frictionless. It's initial height
above the bottom of the loop is ?h = 3R and the
block starts at rest.
What is the magnitude of the normal force that the track of the
loop exerts on the block at position 2? You can assume that the
block is exactly at the horizontal height of the center of the loop
when it reaches position...

2. A bead slides without friction on the loop–the–loop track below. The bead is released from rest at a height h = 4R where R is the radius of the circular section of the track. (a) Using energy considerations, find the speed of the bead at the highest point of the circular section A. (b) Determine the radial component of the equation of motion for the bead at point A. (c) Hence calculate the normal reaction force on the bead...

Consider the small cube of mass m in the figure. It
slides down a circular path of radius R carved into a
large block of mass M. M rests on a table, and
both blocks move without friction (i.e. M can easily slide
sideways). The blocks are initially at rest, and m starts
from the top of the path.
Find the velocity of m as it leaves the block.

As shown in the figure below, a block of mass m starts from rest and slides on a frictionless loop-the-loop track with a loop radius of r. Determine the minimum release height h in order for the block to maintain contact with the track at all times. Express your answer in terms of the radius of the loop, r. h = lo

I need help with the last three questions
the Loop A mass m -82 kg slides on a frictionless track that has a drop, followed by a loop-the-loop with radius R 7.8 m and finally a flat straight section at the same height as the center of the loop (17.8 m off the ground). Since the mass would not make it around the loop if released from the height of the top of the loop (do you know why?) it...

Problem 1: Looping. The looping of a roller coaster has the radius R. The roller coaster starts at rest in height H over the deepest point of the looping (as shown in the figure). Neglect friction and consider the roller coaster as a mass point of mass m. Q.1) Express the total energy of the body. The reference point for the potential energy is at the center of the loop. Q.2) Find the speed of the body at the top...

Loop the Loop Figure 1)A roller coaster car may be approximated by a block of mass m. The car, which starts from rest, is released at a height h above the ground and slides along a frictionless track. The car encounters a loop of radius R as shown. Assume that the initial height h is great enough so that the car never loses contact with the track. Figure 1 of 1 위부

A box slides from rest down a frictionless ramp inclined at 38.0° with respect to the horizontal and is stopped at the bottom of the ramp by a spring with a spring constant of k = 2.00 x 104 N/m. If the box has a mass of 12.0 kg and slides 3.00 m from the point of release to the point where it comes to rest against the spring, determine the compression of the spring when the box comes to...
