Hello everyone,

I am having some trouble with the following two kinematic problems and I would appreciate any help or hints.

Thank you!

---

1. Two rugby players are running towards each other. They are 37 m apart. If one is accelerating from rest at [tex] 0.5 m/s^2 [/tex] and the other was already moving at 3.1 m/s and maintains her speed,

a) how long before they crunch together?

b) how fast was the accelerating player going?

My Work :

I am unsure of this, but I think I would need to set two equations equal to each other: each equation representative of each of the two rugby players. However, I do not know which equations I would need to set equal to each other.

2. A police car stopped at a set of lights has a speeder pass it at 27.78 m/s. If the police car can accelerate at [tex] 3.6 m/s^2 [/tex],

a) how long does it take to catch the speeder?

My Work :

I think that the concept is the same; I would need to set one equation for the police car and one for the speeder equal to each other.
