1. You jump from the top of a boulder to the ground 1.5m below. Estimate your deceleration on landing. 2. v = v0 + at, x = x0 + v0t + 0.5at^2, v^2 = v0^2 + 2a(x-x0) 3. I initially thought that it was gravity (-9.8 m/s) but it's not the answer. I also tried making v into 0 and solving for v0 but it ends up wrong too. I don't understand why it isn't just gravity..is this not a free fall? I'm going crazy..please help!
