Help please I don't no how to do these The curved section of a horizontal highway is a circular unbanked areof radius 760 m. If the coefficient of statiefriction between this roadway and typical tires is 0.40m, what would be the maximum safe driving speed for this horizontal curved section of highway? When a car goes around a banked circular curve at the proper speed for the banking angle, what force cause it to follow the circular path? gravity the...
At the top of a looped section of roller coaster track, the car and rider are completely upside down. What information is necessary to calculate the minimum speed of the car that will prevent a rider from falling out of it? Assume the rider is not strapped into the car. A.) the radius of the loop, the mass of the rider. and the mass of the car b. the mass of the rider and the width of the track c....
2 A student places an object with a mass of mon a disk at a position r from the center of the disk. The student starts rotating the disk. When the disk reaches a speed of 0.8 m/s, the object starts to slide off the disk. What is the coefficient of static friction between the object and the disk? (4 pts) let the radius be 0.1 meters and the mass will be 2.0 Kilograms 1 3. A car with mass...
An object is under the influence of three forces. Two are known: (2.10 N, 0 N) and (-2.10 N, 3.40 N). (a) What is the magnitude of a third force, such that the net force is zero? N (b) What is the direction of degrees counterclockwise from the axis
Three forces are applied to an object, as indicated in the drawing. Force F with arrow1 has a magnitude of 29.0 newtons (29.0 N) and is directed 30.0° to the left of the +y axis. Force F with arrow2 has a magnitude of 21.5 N and points along the +x axis. What must be the magnitude and direction (specified by the angle θ in the drawing) of the third force F3 such that the vector sum of the three forces...
Three forces are applied to an object, as indicated in the drawing. Force 1 has a magnitude of 22.0 newtons (22.0 N) and is directed 30.0° to the left of the +y axis. Force 2 has a magnitude of 19.0 N and points along the +x axis. What must be the magnitude and direction (specified by the angle θ in the drawing) of the third force 3 such that the vector sum of the three forces is 0 N? magnitude...

Recitation Work - 5 In order to get full credit, you need to show all your work. question 1. A force Fx = cx^3 (c = 3.0 N/m^3) acts on an object with mass 40 kg that is sliding along a rough horizontal floor (x-axis) with coefficient of kinetic friction of 0.2. A) What is the work done by the force Fx on this object as it slides from x1 = 0.0 m to x2 = 6.0 m? B) What...
Two forces of 200 N each are applied to an object, such that they are at 140 degree from each other. what is the magnitude of the third force necessary to keep the object stationary? A satellite in a stable circular orbit around the Earth, travelling at 2.3 Times 10^2 km above the ocean has a period of The planet Venus has a period of 225 days in its orbit around the sun. The mean radius of its orbit is:...
1. A roller coaster has a 300 kg car. Assume the track is frictionless. a) The car starts at a speed 20 m/s on a horizontal track. It then goes through a circular loop. What is the speed of the car when it is at the top of the loop, h = 10 m above the horizontal track? b) What is the normal force applied from the track at the point? Does this force point upward or downward? Assume the...
