You push an object, initially at rest, across a frictionless floor with a constant force for a time interval Δt, resulting in a final speed of υ for the object. You then repeat the experiment, but with a force that is twice as large. What time interval is now required to reach the same final speed υ?(a) 4 Δt (b) 2 Δt (c) Δt (d) Δt/2 (e) Δt/4
