Question

what is an expression for x1(t) , the position of mass i as a function of time? assume that the position is measured in meters and time is measured in seconds. express your answer as a function of t . express numerical constants to three significant figures.

Answer 1

The expression for x₁(t) as a function of time is x₁(t) = -3i² m.

Step-by-step explanation:

The position of an object as a function of time is given by the equation x(t) = -3t² m. To find the expression for x₁(t), we substitute i for t in the given equation. So, x₁(t) = -3i² m.

Answer 2

The position of mass i as a function of time can be expressed as x1(t) = 4.0 + 2.0t m.

Step-by-step explanation:

The position of mass i as a function of time can be expressed as x1(t) = 4.0 + 2.0t m. This equation represents the position of the particle as it moves along the x-axis. The constant term 4.0 represents the initial position of the particle at t=0 seconds, and the term 2.0t represents the displacement of the particle as time increases.
