What does the function f(t) = 3t^2 + 4t + 25 represent in the context given?

• The acceleration of an object at any time (t)

• The speed of an object at any time (t)

• The position of an object at any time (t)

• The force acting on an object at any time (t)

What does the first derivative of the function f(t) tell you about object x?

• The position of object x

• The speed of object x

• The acceleration of object x

• The force acting on object x

What does the second derivative of the function f(t) tell you about object x?

• The position of object x

• The speed of object x

• The acceleration of object x

• The force acting on object x

According to the image, what is the relationship between velocity and time graph slope?

• Velocity is the slope of the acceleration vs. time graph

• Velocity is the slope of the position vs. time graph

• Acceleration is the slope of the position vs. time graph

• Acceleration is the slope of the velocity vs. time graph

What is the relationship between acceleration and time graph slope?

• Acceleration is the slope of the position vs. time graph

• Acceleration is the slope of the velocity vs. time graph

• Velocity is the slope of the acceleration vs. time graph

• Velocity is the slope of the position vs. time graph

According to the new theory, how must an electron be described?
