constant force FA is applied to an object of mass M, initially at rest. The object moves in the horizontal x-direction, and the

force is applied in the same direction. After the force has been applied, the object has a speed of vf. Which mathematical routines can be used to determine the time in which the force is applied to the object of mass M

Answer:

Explanation:

When a force is applied for time t , it creates impulse . The impulse creates change in momentum .

In the change in momentum = Mvf - 0 = Mvf .

Impulse =  FA x t , t is time .

FA x t = Mvf

t = M x vf / FA .

leva [86]

Answer:

a) The total force is 4659.8 N

b) The gauge pressure is 50764 Pa

Explanation:

Given:

Pressure inside = 0

Patm = pressure outside = 1.013x10⁵Pa

Pressure difference = ΔP = 1.013x10⁵ - 0 = 1.013x10⁵Pa

a) The area is equal:

A=12*6=72in^{2} =0.046m^{2}

The force is:

F=delta-P*A=1.013x10^{5} *0.046=4659.8N

b) The gauge pressure at the bottom is equal:

P=\rho gh

Where:

ρ = density = 1000 kg/m³

h = 17 ft = 5.18 m

Replacing:

P=1000*9.8*5.18=50764Pa

Amanda [17]

Answer:

Explanation:

  We shall apply concept of Doppler's effect of apparent frequency to this problem . Here observer is moving sometimes towards and sometimes away from the source . When observer moves towards the source , apparent frequency is more than real frequency and when the observer moves away from the source , apparent frequency is less than real frequency . The apparent frequency depends upon velocity of observer . The formula for apparent frequency when observer is going away is as follows .

f = f₀ ( V - v₀ ) / V , f is apparent , f₀ is real frequency , V is velocity of sound and v is velocity of observer .

f will be lowest when v₀ is highest .

velocity of observer is highest when he is at the equilibrium position or at middle point .

So apparent frequency is lowest when observer is at the middle point and going away from the source  while swinging to and from before the source of sound .
