Alexandra is attempting to drag her 32.6 kg golden retriever across the wooden floor by applying a horizontal force. What force

vichka [17]

Answer:

230.26 N

Explanation:

Since the speed is constant, acceleration is zero hence the net force will be given by the product of mass, coefficient of friction and acceleration due to gravity

F=0.72*32.6*9.81=230.26 N

sergeinik [125]

Answer:

Density of unknown liquid is $2047 kg/m^3$

Explanation:

When rock is suspended in air then the weight of the rock is counter balanced by the tension force in the string

So here we have

$T = mg = 43.8 N$

now when the rock is immersed in water then the tension in the string is and buoyancy force due to water is counter balanced by the weight of the object

so here we have

$T_1 + F_b = mg$

$31.3 + F_b = 43.8$

$F_b = 43.8 - 31.3 = 12.5 N$

now we have

$(1000)V(9.81) = 12.5$

$V = 1.27 \times 10^{-3} m^3$

now when the rock is immersed into other liquid then we have

$T_2 + F_b' = mg$

$18.3 + F_b' = 43.8$

$F_b' = 25.5 N$

now we have

$\rho(1.27 \times 10^{-3})(9.81) = 25.5$

$\rho = 2047 kg/m^3$

The magnitude of the velocity vector of the car is ∣∣v→∣∣ = 78 ft/s. If the vector v→ forms an angle θ = 0.09 rad with the horiz

kotegsom [21]

Answer:

$\vec{v} = (77.68~{\rm ft/s})\^i + (7.01~{\rm ft/s})\^j$

Explanation:

The x- and y- components of the velocity vector can be written as following:

$\vec{v}_x = ||\vec{v}||\cos(\theta)\^i$

$\vec{v}_y = ||\vec{v}||\sin(\theta)\^j$

Since the angle θ and the magnitude of the velocity is given, the vector representation can be written as follows:

$\vec{v} = 78\cos(0.09)\^i + 78\sin(0.09)\^j\\\vec{v} = (77.68~{\rm ft/s})\^i + (7.01~{\rm ft/s})\^j$
