Hi everyone, i have a exam coming up for Physics and this question from the kinematic unit is really bothering me. I've tried many times but i have no idea how to solve it. Some help would be greatly appreciated, thanks.(adsbygoogle = window.adsbygoogle || []).push({});

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

Question: Town A and Town B are 6.0 x 10^2 (600) meters apart. Kevin leaves Town A and heads for Town B at a constant speed 30m/s. Peter leaves Town B at the same time and heads for Town A at an acceleration 1.5 m/s^2 from rest.

a) at what distance from Town A will they meet each other?

b) How much time passes before they meet?

2. Relevant equations

I used only this equation so far

Delta d = (Velocity 1)( delta time) + 1/2 (acceleration) (delta time)^2

3. The attempt at a solution

I've stated some of the unknowns from Kevin and Peter, and found only the following.

Kevin-

Velocity 1 = 30 m/s

displacement Kevin = Displacement Peter

Peter-

acceleration = -1.5

velocity 1 = 0

displacement Peter = Displacement Kevin

Using those information i tried connecting the two equations with the same unknown variable. But I only got one equation, and it was for Peter.

delta D = v1(t) + 1/2 (a)(t)^2

= 0(t) + 1/2(-1.5)(t)^2

= -0.75(t)^2
