Answer:
0.1575 m/s^2
Explanation:
Solution:-
- Acceleration ( a ) is expressed as the rate of change of velocity ( v ).
- We are given that the trains starts from rest i.e the initial velocity ( vo ) is equal to 0. Then the train travels from reference point ( so = 0 ) to ( sf = 5.6 km ) from the reference.
- During the travel the train accelerated uniformly to a speed of ( vf =42 m/s ).
- We will employ the use of 3rd kinematic equation of motion valid for constant acceleration ( a ) as follows:
- We will plug in the given parameters in the equation of motion given above:
Answer: the acceleration during the first 5.6 km of travel is 0.1575 m / s^2
If someone with anger issues is struggling to control their temper, great tips are:
1. Find something in your life that you've been through that may relate to what this person is angry about, and calmly share your story. For example, Tom is abnormally angry about not getting his new tool kit delivered on time. So you say, "I understand, one time I waited weeks for my phone case to come in and it upset me very much."
2. Take the angered individual to an isolated and private area. This gives them less triggers and is safer for others.
3. Teach the person coping skills when they are NOT currently having an episode. For example, Chloe is in a good mood while she is painting her nails. So you say, "Can I show you a coping skill for anger I found online? Its awesome! Just tense up every muscle in your body as hard as you can for 5 seconds, then release the tension slowly for 10 seconds. Repeat until you feel cooled down. Try it!"
4. If someone's anger problems become a threat to themselves or those around them, take this person to see a professional. It could be serious!
Elastic
☑ occur when the colliding objects bounce off of each other
☑ hard or bouncy objects
☑ kinetic energy is conserved
Inelastic
☑ occur when two objects collide
☑ two objects colliding stick together
☑ kinetic energy is not conserved — some of the initial kinetic energy is converted into other types of energy (heat, sound, etc.)
