4. Calculate the slope of the line in your graph of the square of the period of the spring vs. mass [slope = (y2 – y1)/(x2 – x1)

]. Robert Hooke figured out the equation that describes the periodic motion of the spring. If you square both sides of the equation, you will find that the slope of the line is related to the spring constant (k). Specifically, slope = 42/k. Use your data to calculate the k of your spring.

A 5 kg ball rolling at 1.0 m/s hits a 15 kg ball at rest. The balls stick together after the collision What is the
Reika [66]

Answer:

0.25m/s

Explanation:

Given parameters

m₁  = 5kg

v₁ = 1.0m/s

m₂ = 15kg

v₂ = 0m/s

Unknown:

velocity after collision = ?

Solution:

Momentum before collision and after collision will be the same. For inelastic collision;

    m₁v₁ + m₂v₂  = v(m₁ + m₂)

Insert parameters and solve for v;

   5 x 1  + 15 x 0 = v (5 + 15 )

          5  = 20v

          v = \frac{5}{20}   = 0.25m/s

What does each system help you do?
Maru [420]

Explanation:

1.The somatic nervous system is the part of the peripheral nervous system associated with the voluntary control of body movements via skeletal muscles. 

2. The autonomic nervous system is a control system that acts largely unconsciously and regulates bodily functions, such as the heart rate, digestion, respiratory rate, pupillary response, urination, ect...

3. Sympathetic Division is a term used by researchers and medical practitioners to describe the subdivision of the autonomic nervous system (that controls involuntary and automatic physical reactions) that responds to emergency situations by mobilizing and controlling the energy necessary to cope with the situation.

4. The part of the autonomic nervous system that tends to act in opposition to the sympathetic nervous system, as by slowing down the heart and dilating the blood vessels. It also regulates the function of many glands, such as those that produce tears and saliva.

5. a regulatory substance produced in an organism and transported in tissue fluids such as blood or sap to stimulate specific cells or tissues into action.

A semi-truck is traveling at 65mph on the freeway and you are traveling in your Ford
Ymorist [56]

Answer:

The vehicle with the most mass

Explanation:

Momentum is the quantity of motion in a body and it is dependent on its mass and velocity.

Momentum  = m x v

m is the mass

v is the velocity

Now,

Both mass and velocity are directly proportional to  momentum. Since the two bodies moves with the same velocity, the vehicle with the most mass will have the greatest momentum
