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 block of mass m slides down a frictionless incline. The block is released a height h above the bottom of the loop. The bottom of the loop is circular with radius R. a) What is the force of the track on the block at point A? Express your answer in terms of m, g, h, and R. b) What is the force of the track on the block at point B? Express your answer in terms of m, g,...
At a height h = 2.0 m on top a frictionless slope, a block with mass m = 2.5 Kg is given an initial velocity v_i = 5.0 m/s before it slides down towards the rough horizontal surface below. If this horizontal surface has a coefficient of kinetic friction mu_k = 0.4, then: what is the blocks speed after traveling 4.0 m on the rough surface? After coming to a stop how much the internal energy of the whole system...
A 5kg block starts at a height of 10m above the ground and slides 20m down a rough surfaced incline. The work done by the frictional force in sliding down the incline is 240 J. It reaches the bottom of the incline and then enters a frictionless vertical loop of radius 2m. The speed of the block at the bottom of the hoop is 10.0m/s. The block performs one revolution and exits the loop.o sinu or mohe imImtombnes biduo nsotinpie...
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
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...

Constants Find the kinetic energy K of the car at the top of the loop. Express your answer numerically, in joules. (Figure 1) A roller-coaster car may be represented by a block of mass 50.0 kg. The car is released from rest at a height h = 48.0 m above the ground and slides along a frictionless track. The car encounters a loop of radius R = 16.0 m at ground level, as shown. As you will learn in the...
The 2-lbm mass m is released down a frictionless track from a height h. If the loop at the bottom has radius 12 inches, what is the minimum h from which the mass can be released so it will go around the loop?
