3. A frictionless 2,000 kg roller coaster starts from rest at ground level (point A) and is raised up a hill to aheight of 55.0 meters (point B) where it pauses briefly. From the top of the hill, the roller coaster racesdown to ground level (point C) before going through a 30.0 m diameter circular loop (point D), and then upto a 15.0 m high plateau (point E) where the roller coaster is brought to a stop over 10.0 m (point F).(a) How much energy does it take to move the roller coaster from point A to point B?(b) What is the velocity of the roller coaster at point C?(c) What is the velocity of the roller coaster at point E?(d) What force must the brakes exert on the roller coaster to bring it to a stóp in 10.0 m?

You are testing a new amusement park roller coaster with an empty car with a mass of 130 kg. One part of the track is a vertical loop with a radius of 12.0 m. At the bottom of the loop (point A) the car has a speed of 25.0 m/s and at the top of the loop (point B) it has speed of 8.00 m/s. As the car rolls from point A to point B, how much work is done by friction? Use 9.81 m/s2m/s2 for the acceleration due to gravity.

Current Attempt in Progress A particle, starting from point A in the drawing (the height at A is 3.00 m), is projected down the curved runway. Upon leaving the runway at point B, the particle is traveling straight upward and reaches a height of 6.39 above the floor before falling back down. Ignoring friction and air resistance, find the speed of the particle at point A. B

A particle, starting from point A in the drawing (the height at A is 3.00 m), is projected down the curved runway. Upon leaving the runway at point B, the particle is traveling straight upward and reaches a height of 6.93 above the floor before falling back down. Ignoring friction and air resistance, find the speed of the particle at point A. Number i Units
When you throw a ball into the air, it usually falls back down. If you throw it a little harder, it will take it longer to fall back down. You can throw it so hard that it never falls back down to Earth. This launch speed is called the escape velocity. When you are far from Earth, the potential energy of an object with mass m can no longer be written as PE = mgh. Instead, we must use the equation М-т PE = -G .. 1" M is the mass of the planet you launch from. m is the mass of the object being launched. r is the distance from the center of the planet to the object being launched. G is a universal constant called the gravitational constant (6.67-10-" ). kg-s Notice that the potential energy is 0 when you are infinitely far away from the planet, and negative as you get closer.
