Students have asked these similar questions
A train typically requires a much greater distance to come to rest,for a given initial speed, than does a car. Why?
Suppose a car accelerates from 69 to 112 km/h?
By what percent does the drag force on a car increase?
Suppose that the highway is icy and the coefficient of friction between the tires and pavement is only one-third what you found in the previous part. What should be the maximum speed of the car so it can round the curve safely?

- Show that the acceleration of any object down an incline where friction behaves simply (that Is, where fk=kN ) is a=(sinkcos) . Note that the acceleration Is independent of mass and reduces to the expression found in the previous problem when friction becomes negligibly small (k=0) .arrow_forwardWe know from studying friction forces that static friction increases with increasing normal force between the surfaces, which becomes important for vehicles traveling on icy or snowy roads that have coefficients of static friction much smaller than those of dry pavement. In particular, the greater the normal force on the drive wheels (those coupled to the engine), the better the traction. The horizontal position of the center of mass of a typical compact automobile is located 1.1 m toward the rear as measured from the front wheel axle. The wheelbase (distance from the front wheel axle to the rear wheel axle) is 2.7 m. Assume the car is stationary on level ground and has a weight of 12,000 N. Determine the total normal force on the two front tires and on the two rear tires. Which do you suppose are the drive wheels in this case?arrow_forwardConsider an aircraft that takes off at 260 km/h when it is fully loaded. If the weight of the aircraft is increased by 10 percent as a result of overloading, determine the speed at which the overloaded aircraft will take off.arrow_forward
- Why is the stopping distance of a truck much shorter than for a train going the same speed?arrow_forwardThe floor of a railroad flatcar is loaded with loose crates having a coefficient of static friction of 0.25 with the floor. If the train is initially moving at a speed of 48 km/h, in how short a distance can the train be stopped at constant acceleration without causing the crates to slide over the floor?arrow_forwardTwo masses are found on the system below. Determine the value of m1 to make the system accelerate 1.43m/s2[m2 <-] assuming m2=3.5kg, and a coefficient of kinetic friction of 0.27 exists between both blocks and their surfaces.arrow_forward
- If the mass of an object is doubled, what happens to the acceleration?arrow_forwardA cake rests in a cardboard box on the horizontal surface of the seat of your car which is traveling at 11 m/s. If the coefficients of friction are µk = 0.3 and µs = 0.5, find the minimum stopping distance necessary to keep the cake box from sliding off the seat.arrow_forwardWhat happens to the coefficient of friction, when weight of the body is doubled?arrow_forward
