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...

The Sidewinder is a shuttle type steel rollercoaster. The rollercoaster cart starts at the bottom of the frictionless track and is accelerated from a stand still over a distance of 7 meters. Then the cart enters the loop, rises to the top with just enough velocity to keep from stalling at the top of the loop. Gaining velocity the cart finishes the loop, bottoms out, and then rises up the vertical segment of the track. After stalling out at a...

You are riding the new rollercoaster Fizzix Phun at your local amusement park. The technician with a mass of 100kg clears your car for 'takeoff'. The rollercoaster car full of people with a mass of 1000 kg is pulled up the initial hill by a lift device. The maintenance stairs up to the top of the hill consists of 11 flights of 30 stairs each wherein a single stair is 10cm high. The drop down the first hill is terrifyingly...

2. Suppose around a loop a 2000 kg roller coaster starts out at 100 m above the ground and slides down and that is 30 meters in radius. Ignoring friction, (a) find the speed at the bottom of the o (the ground) and at the top of the loop? (o) What is the centripetal acceleration and normal and label all the force at the bottom of the...

A 150g ball slides down a perfectly smooth incline starting at a height of 2.44m, at rest. At the bottom of the incline is strikes and sticks to a 280g block. The block/ball combo are then free to move along a frictionless rollercoaster track. The first hill is only 23 cm high. Can it make it over this first hill? Defend your response with detailed analysis. If the combo CAN make it over the hill, how fast is it moving...

A car on a roller coaster starts at zero speed at an elevation above the ground of 20.8 m. It coasts down a slope, and then climbs a hill. The top of the hill is at an elevation of 14.77 m. What is the speed, in m/s, of the car at the top of the hill? Neglect any frictional effects; g=9.80 m/s2. A projectile is shot from the surface of Earth by means of a very powerful cannon. If the...

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...

A block starts from rest and slides down a smooth ramp of height h. When it reaches the bottom it is moving at speed v. It then continues to slide up a second smooth ramp. What is the velocity up the second ramp at the point the potential energy is equal to the kinetic energy? 1. v/2 2. v/3 3. v/4 4. v 5. sqrt(3)v/ 6. sqrt(2)v/

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...
