What is the momentum of a 0.145 kg baseball traveling at 40.0 m/s
dimulka [17.4K]
Answer: 5.8 kg m/s

Identify the given information.
m = 0.145 kg
v = 40.0 m/s

Choose which formula you should use. In this case, you are finding momentum.
p = mv, where p is momentum.

Substitute and solve.
p = 0.145 kg x 40.0 m/s
p = 5.8 kg m/s

As a freely falling object picks up downward speed, what happens to the power supplied by the gravitational force?
vitfil [10]

We will start from the definition of power in terms of the Force. Power could be described as the change of energy in an instant of time. Considering that Energy is the product between the Force and the distance traveled we would arrive at the expression

P = \frac{E}{t}

P = \frac{F*h}{t}

Here,

F = Force

h = Height

t = Time

As there is no external force, apart from the force of gravity, and this, is constant during the course of the object we will also have to be constant power and therefore this during its course will be the same. The correct answer is (1)

Describe the relationship between the direction of the velocity vector and the direction of the acceleration or a body moving in
Law Incorporation [45]

In the centripetal movement, what happens with velocity is that it will remain constant, always pointing in its tangential direction of the trajectory. Said speed, although constant, will have a constant direction that will generate an acceleration that will always point towards the center of the circle radius. Both vectors as the turn is performed will always be perpendicular to each other.

Speakers A and B are vibrating in phase. They are directly facing each other, are 8.2 m apart, and are each playing a 78.0 Hz to
Stels [109]

Answer:6.298,4.1,1.9015

Explanation:

Wavelength=\frac{velocity of sound }{frequency}

=\frac{343}{78}=4.397 m

Distance of 3rd speaker from speaker A is x

From B 78-x

Difference between the distances must be a whole number of wavelengths

First

x-\left ( 8.2-x\right )=4.397    for 1 st wavelength

2x=8.2+4.397=12.597

x=6.298m

second

For zero wavelength

x-\left ( 8.2-x\right )=0

2x=8.2

x=4.1m

Third

\left ( 8.2-x\right )-x=4.397

x=1.9015 m
