If a car goes through a curve too fast, the car tends to slide out of the curve. for a banked curve with friction, a frictional force acts on a fast car to oppose the tendency to slide out of the curve; the frictional is directed down the bank (in the direction water would drain). consider a circular curve of radius r = 200 m and bank angle (theta), where the coefficient of static friction between tires and pavement is (mu-static). a car (without negative lift) is driven around the curve as shown in the diagram. (a) find an expression for the speed vmax that puts the car on the verge of sliding out. (b) on the same graph, plot vmax versus angle (theta) for the range of 0 degrees to 50 degrees, first for (mu-static) = 0.050. (now i hope you can see why accidents occur in highway curves when icy conditions are not obvious to drivers, who tend to drive at normal speeds.

an energy transformation flow diagram is shown

where is it ?

dec 23, 2016 - a load of bricks weighing 680 n a distance of 10 m across a parking lot. if if the worker pushes the cart with a constant force of 209 n, what work= force x distance = 220 n x 10 m = 2200 n.m = 2200 j i don't know where the person got it from, but the initial part, work= force x distance me.

  the unit of the measure =

explanation:

  the property that is quantified by the energy needed per of material to raise the temperature by one.

  si unit of energy = joule (j)

  si unit of temperature = kelvin (k)

  si unit of mass of material = kilogram (kg)

the property that is quantified by the energy needed per of material to raise the temperature by one is called specific heat.

the unit of specific heat is

the temperature in kelvin of 2.0 dm3 of an ideal gas is doubled and its pressure is increased by a factor of four. what is the final volume of the gas
