Question

The position of an electron is given by x = 2t + 3t² with t in seconds.

A) Constant velocity
B) Acceleration
C) Simple harmonic motion
D) Uniform circular motion

Answer 1

The position equation x = 2t + 3t² represents a motion with acceleration.

Step-by-step explanation:

The position of an electron is given by x = 2t + 3t² with t in seconds. To determine the motion represented by this equation, we can analyze its components. The term 2t represents a linear term, which means that the electron is moving with a constant velocity. The term 3t² represents a quadratic term, which means that the electron is experiencing acceleration. Therefore, the correct answer is B) Acceleration.
