## Homework Statement

http://cyclotron.tamu.edu/dhy/sample_exam1_phys218.pdf [Broken]

For Number 2 Part a

## Homework Equations

v0 = 1.7 m/s

F = ma

v = 0m/s

v² = v0² + 2aΔx

## The Attempt at a Solution

Spent like 30 minutes trying to use a constant acceleration kinematics equation, but nothing seemed to work without knowing either the time or the acceleration.

Then I remembered that F = ma, and the problem gave me the force (9.8*10^4N) and the mass (3.6*10^7kg). So I solved for a, and got -0.00272 m/s².

I plugged this acceleration into v² = v0² + 2aΔx and solved for Δx, and I got 530.82 meters. Is this correct? If not, can anyone help me understand what I did wrong?
