To determine the time until collision between the two rugby players, we need to calculate the time it takes for Player 1 to reach the position of Player 2.

Given: Initial distance (d) = 37 m Player 1 acceleration (a1) = 0.5 m/s^2 Player 2 velocity (v2) = 3.1 m/s

Let's calculate the time until collision:

First, we'll find the time it takes for Player 1 to reach the position of Player 2.

The equation to calculate the distance traveled by an object with constant acceleration can be used here: d = (1/2) * a * t^2

For Player 1: Initial velocity (v1) = 0 m/s (starting from rest) Acceleration (a1) = 0.5 m/s^2 Distance traveled (d1) = distance between the players = 37 m

Using the equation: d1 = (1/2) * a1 * t1^2

Rearranging the equation: t1^2 = (2 * d1) / a1

Substituting the values: t1^2 = (2 * 37 m) / 0.5 m/s^2 t1^2 = 74 s^2 / 0.5 m/s^2 t1^2 = 148 s^2 t1 ≈ √148 s t1 ≈ 12.165 s

So, it takes Player 1 approximately 12.165 seconds to reach the position of Player 2.

Since Player 2 has a constant velocity and is moving the whole time, we can assume that Player 2 has been running for the same amount of time.

Therefore, the time until collision is approximately 12.165 seconds.
