1. A sprinter runs at a forward velocity of 11.9m/s. If the sprinter has a mass of 77.4kg, what is the sprinter’s kinetic energy? 2. A car having a mass of 654kg has a kinetic energy of 73,700J. What is the car’s speed?

3. A rock is rolling down a hill with a velocity of 4.67m/s. It has a kinetic energy of 18,900J. What is the mass of the rock?

4. Calculate the kinetic energy of an airliner with a mass of 7,600kg that is flying at a speed of 147m/s.

plz help as this will help my grade

the correct answer is 4) heat and pressure

metamorphic rocks arise from transformation of existing rocks types, in a process called metamorphism. during metamorphism the original rock(prolith) change into metamorphic rock by heating (150-200c) and pressure of more than 1000 bar. the original rock can be sedimentary, igneous, or existing metamorphic rock.

measured, submerged.

answer;

-vessels in the chest

the diagnosis of angina pectoris literally means "vessels in the chest"

explanation;

-angina pectoris is the medical term for chest pain or discomfort due to coronary heart disease.it is the chest pain due to an inadequate supply of oxygen to the heart muscle. the pain is typically severe and crushing, and it is characterized by a feeling of pressure and suffocation just behind the breastbone.

agina pectoris is caused by reduced blood flow to your heart muscle. the blood carries oxygen, which the heart muscle needs to survive. when the heart muscle isn't getting enough oxygen, it causes a condition called ischemia
