Answer:
2.5
Step-by-step explanation:
Let x = hours to meet
train one has a 2 hour head start or 210 km head start
210 + 105x = 135x
30x = 210
x = 7 hours to meet
What is the net of the shape? I would say a ball, or a cylinder.
Answer:
it is not a prim number because ONE is not greater than ONE and it is not composite because in that case you can not multiply or divide one by its self
Step-by-step explanation:
in order for a number to be prim you have to have it only be able to be multiplied by one to get the answer but it has to be greater than one. in order for a number to be composite it has to have at least one divisor other than one its self
hope it helps and happy studding
The linear function that maps the relation between kinetic energy and mass is given at the end of the question.
<h3>What is the kinetic energy of an object?</h3>
The kinetic energy of an object is given by the following formula:
E = 0.5mv².
In which:
- m is the mass of the object.
- v is the velocity of the object.
In this problem, we suppose a velocity of 2.5 m/s, hence the kinetic energy is:
E = 0.5m(2.5)² = 3.125m.
Hence the graph is plotted at the end of the answer.
