In this question assume the sound speed in air is 343 m/s. A goose flying toward you at 11.4m/s emits a squawk, which you hear at 262Hz.
a) Find the wavelength of the sound you hear.
b) Find the wavelength of the sound you hear if the goose emits the same squawk while flying away at the same speed?
Find the horizontal component of the force exerted on the rod by the hinge and Find the vertical component of the force exerted on the rod by the hinge.
Illustrate what average power must the winch supply in order to accelerate a 174-kg ultra-light glider from rest to 23.0 m/s over a horizontal distance of 50.0 m? Assume that friction and air resistance are negligible, and that the tension in the ..
A shell, fired from a cannon, has a muzzle speed (the speed as it leaves the barrel) of 800 ft/s. The barrel makes an angle of 45o with the horizontal and, for ease; the barrel opening is assumed to be at ground level.
Using and Atwood machine with masses m1 and m2, at first with m1 a distance 2h above m2, what is the speed of either mass they pass each other? Make use of energy to solve (hint they cross halfway between the starting positions of the two masses).
Two boats are initially separated by distance d and head directly toward one another. The skippers of the boats want to arrive at the same time at the point that is halfway between their starting points.
A large wooden turntable in the shape of a flat uniform disk has a radius of 2.00 m and a total mass of 120kg. The turntable is initially rotating at 3 rad/s about a vertical axis through its center.
A particle moving along the x-axis has its position described by the function x =( 5.00 t3? 3.00 t+ 2.00 )m, what are the particle's position, velocity and acceleration
If the beam now strikes the top of a building standing directly at the water's edge, find out the height of the building.
define the magnitude of the acceleration of the elevator. A 300 kg piano slides 4.1m down a 30 degree incline and is kept from accelerating by the man who is pushing back on it parallel to the incline. The effective coefficient of kinetic friction ..
