1. The problem statement, all variables and given/known data I seem to have a fundamental misunderstanding of the kinematic principles in this question. A constant force of 8.0N is exerted for 4.0s on a 16-kg object initially at rest. What will the change in speed of this object be? 2. Relevant equations F = ma Δx = v0t + 1/2 at2 Δv = v0 +at Δv = Δx/Δt Δv = v0 + aΔt 3. The attempt at a solution F = ma thus a = (8.0N) / (16.0 kg) = .5 m/s^2 then Δx = (0 m/s)(4 s) + 1/2(.5 m/s^2)(4 s)^2 = 4 m if Δv = Δx/Δt then Δv = (4 m) / (4 s) = 1 m/s but using Δv = aΔt Δv = (.5 m/s^2)(4 s) = 2 m/s I don't understand why I would have two conflicting answers there. Just curious if anyone might have some insight on why that would be. Thanks!
