(adsbygoogle = window.adsbygoogle || []).push({}); [SOLVED] Kinematic motion problem. (acceleration, displacement, velocity)

1. The problem statement, all variables and given/known data

Two rugby players are running towards each other. They are 37 m apart. If one is accelerating from rest at 0.5 m/s^2 and the other was already moving at 3.1 m/s and maintains her speed. (brackets are answers from textbook)

a) how long before they crunch together? (7.5 seconds)

b) how fast was the accelerating players going? (3.8 m/s)

c) how far has each player run? (14 m, 23 m)

2. Relevant equations

Not sure.

3. The attempt at a solution

player 1:

a=0.5 m/s^2

initial velocity=0 m/s (started from rest)

player 2:

speed = 3.1 m/s

d= 37 m

for b) Would I have to convert the acceleration to speed? Is that even possible?

c) is it asking how far each person has to run in order to run the entire 37m? or just when they "crunch" together.

I'm not sure where to start. There isn't much information to use the equations.
