Answer 2

Equation of Motion for Two Bodies

The equation of motion for two bodies can be represented by the following equations:

1. 215.08t + x = 0 2. 2124t - x = 0

Where: - t represents time in seconds, - x represents the distance between the two bodies in meters.

To determine the meeting point and time, we need to solve these equations simultaneously. By solving the equations, we can find the value of t and x at the point of intersection.

Solving the Equations

To find the meeting point and time, we can solve the equations as follows:

1. 215.08t + x = 0 - Rearranging the equation, we get: x = -215.08t

2. 2124t - x = 0 - Rearranging the equation, we get: x = 2124t

By equating the two expressions for x, we can solve for t:

- -215.08t = 2124t - Solving for t, we find: t = 0

Substituting the value of t back into either equation, we can find the value of x:

- Using the first equation: x = -215.08(0) = 0

Therefore, the meeting point of the two bodies is at x = 0 meters, and the time of intersection is t = 0 seconds.

Distance Between the Bodies after 4 seconds

To find the distance between the two bodies after 4 seconds, we can substitute t = 4 into either equation and solve for x:

- Using the first equation: x = -215.08(4) = -860.32 meters

Therefore, the distance between the two bodies after 4 seconds is 860.32 meters.
