There are two football players standing 48 meters apart (player A and player B). They start running towards each other. Player A acceleration is 0.5 m/s2 and player B acceleration is 0.3 m/s2.

How much time passes before each player collides with each other?

When they collide how far has the first player(player A) traveled?

#### Solution Preview

I will use the notation "_" to designate a subscript.

Total distance traveled = S_Total = 48 m.
Total, effective acceleration = A_total = 0.5 + 0.3 ...

#### Solution Summary

This is a step-by-step solution showing the time taken for two objects travelling towards each other with uniform accelaration.
