1. The problem statement, all variables and given/known data A slight earth tremor causes a large boulder to break free and start rolling down the mountainside with a constant acceleration of 5.2 m/s^2. What is the boulder's velocity after 5.0s. 2. Relevant equations I used: v2 = v1 + a x Δt 3. The attempt at a solution v1 = 0 [because it started to break free] a = -5.2m/s^2 [because of the sign convention down] Δt = 5.0s v2 = ? [because it is finding velocity after 5.0s] ok it was v2 = 0 + (-5.2m/s^2)(5.0s) v2 = -26 m/s Am I correct or have a done a simple mistake that would impact my answer?
