How much do the roller coaster carts weigh? To be stable, the force exerted by the ground must be on a line going through the center of gravity. When you push a piece of chalk across a chalkboard, it sometimes screeches because it rapidly alternates between slipping and sticking to the board. As you can see, the mass of car (and riders) $m$ does play part here but again it seems folly to rely on loading specifications rather than safe design. > rollercoaster carriage? @user3591496: welcome. Describe the path of the car as it leaves the road. The kinetic friction force between two materials moving relative to each other is determined using the coefficient of kinetic friction, which also depends on both materials and is always less than the coefficient of static friction.

At the start of the ride, when $v=0$, the Total Energy $T$ was: $T = mgh_1$ and when the car reaches the lowest point $h_3$, then: Note something important here: the expression for $v$ does not contain the mass $m$ of the car (and riders). Venus takes, Q:A particular gasoline tank can hold 48.5 kg of gasoline when full. Height is #h//2,:. Because you are given information about the motion of the roller-coaster, you can solve for force using energy (or Newtons Second Law) rather than plugging into the definition of friction.

Some books teach you to always think about this term, others only add it if it isnt zero. A 1000 kg roller coaster begins on a 10 m tall hill with an initial velocity of 6m/s and travels down before traveling up a second hill. a=3.90 cm , b=2 a=7.8 cm , c=2.4 a=9.36 cm. At what angle relative to the vertical does the plumb bob hang? What is the normal force between the piston and cylinder? Are we talking about filled with fat ACErs or without? We are given complete information about the energy of the roller-coaster at Point A and are asked about the force required to stop it by Point D. Therefore, the second question can be answered by comparing A and D. Because the energy in the roller-coaster is the same from A to C, it is equally fine to compare B to D or C to D (if you solve for vC first.). The magnitude of static friction force between two materials stationary relative to each other is determined using the coefficient of static friction, which depends on both materials.
