A ski starts from rest and slides down a 22° incline 90 m long. Use energy methods.
(a) If the coefficient of friction is 0.09, what is the ski's speed at the base of the incline?
_____m/s
(b) If the snow is level at the foot of the incline and has the same coefficient of friction, how far will the ski travel along the level?
______m
A charged cloud system produces an electric field in the air near Earth's surface. A particle of charge -1.6 x 10-9 C is acted on with a downward electrostatic force of 4.5 x10-6 N when placed in this field. What is the magnitude of the electric fie..
At one instant a bicyclist is 43 m due east of a park's flagpole, going due south with a speed of 12 m/s. Then 22 s later, the cyclist is 43 m due north of the flagpole, going due east with a speed of 12 m/s.
The drawing shows three situations — A, B, and C — inwhich an observer and a source of electromagnetic waves are movingalong the same line. In each case the source emits a wave that hasa frequency of 4.57 x 1014 Hz.
A factory worker pushes a 28.0kg crate a distance of 4.8m along a level floor at constant velocity by pushing downward at an angle of 28 below the horizontal. How much work is done by the normal force
If the flow of blood is to remain constant through the aorta the velocity of blood must increase from 26.5 cm/sec to 40 cm/sec as the radius decreases from 1 cm to 0.8 cm. Calculate the pressure difference between these two areas of the aorta
Two systems are formed from a converging lens and a diverging lens, as shown in parts a and b of the drawing. (The point labeled "Fconverging" is the focal point of the converging lens.) An object is placed inside the focal point of lens 1 at a dista..
A heating element in a stove is designed to dissipate 3380 W of heat when it is connected to 200 V. Assuming that the resistance is constant, Calculate the power the heating element dissipates
When Jeff ran up a hill at 6.0 m/s, the horizontal component of his vector was 4.5 m/s. What was the vertical component of Jeff's velocity?
What is the total negative charge, in coulombs, of all the electrons in a small 1.05 gram sphere of carbon? One mole of carbon is 12 grams
A steel wire of mass 0.400kg and length 0.640m supports a 102 kg block. The wire is struck exactly at its midpoint causing a small displacement. How long does it take the peak of this displacement to reach the top of the wire.
A parallel-plate vacuum capacitor, with its plates separated by a distance of x1 has an amount of energy equal to U stored in it. The separation is then decreased to X2
